Diesel Engines Forgotten Treasures

Diesel Engines Forgotten Treasures – There are very few engine configurations that promise increased fuel economy and power. There are few engines that offer this in addition to reliability. Today, those across the ocean are enjoying the  fruits of diesel technology revolution.

Diesels have experienced a great history here in the United States. In 1980, General Motors modified  their 350ci gas V8 to run on diesel fuel. The result however, wasn’t that god. These engines offered better fuel economy but little else. They were very slow, and not very reliable.

Mercedes Benz on the other hand, had better luck in the 1980s with an array of vehicles available with diesel engines. These great vehicles offered amazing durability although they were rough, noisy, and smoked quite a bit. Volkswagon offered diesel as well, although they had a habit for spewing blue smoke from the tail pipe.

Throughout the 90s, Benz and Volkwagon offered diesel vehicles in the United States, with each generation becoming cleaner, smoother, and more powerful than the last. Overall, they were a tough sell as they still lacked the horsepower
that many were seeking.

Today, Mercedes, BMW, Jaguar, Volkswagon, Ford, and many other manufacturers are offering diesels to many markets throughout the world. To put it simple, forget everything you know or think you know about diesel engines in the United States.

These newer engines benefit from hundreds of technical innovations. There are several diesels in Europe that offer better acceleration than their gasoline counter parts. BMW’s 120d has 163bhp, goes 0 – 60 in under 8 seconds, and achieves 49.6 miles per gallon.

Benz offers the C320 CDI SE that has 224bhp, and over 360 lb foot of torque. This car gets just under 48 mpg on the highway, with an acceleration of 0 – 60 in under 7 seconds. Throughout North America, you won’t find a gasoline engine that offers this unique blend of fuel economy and excellent performance.

The reason why diesels haven’t caught on in  North America comes down to one word – sulfur. We have too much sulfur in the diesel here in the United States. This cheap grade of diesel fuel will run havoc on the more sophisticated diesels
offered overseas and cause an increase in emissions.

There is hope however, as refiners will soon be producing what is known as ultra low sulfur diesel fuel. This will help to reduce the sulfur content from 500ppm to 15ppm.

 

Heavy Equipment Courses Led To Important Role In Automotive Field

Summary: In-school theory, lab practice and a paid co-op placement are three key components that make Centennial Colleges Heavy Duty Equipment Technician courses stand apart from those of other schools.

In the automotive industry, Heavy Duty Equipment Technicians have a variety of important responsibilities. First and foremost, they are responsible for checking bulldozers, cranes, graders and other heavy construction, agricultural, logging and mining equipment for proper performance and inspect equipment to detect faults and malfunctions. As such, jobs can be found in a variety of areas. In addition, Heavy Duty Equipment Technicians diagnose the faults or malfunctions; adjust equipment and repair or replace defective parts, components or systems; test repaired equipment for proper performance and to ensure that work meets manufacturers specifications; and much more. In addition to Heavy Duty Equipment Technicians, this field also has a need for service managers, service writers or coordinators, equipment company representatives, or college or industry teachers.

Training is available at Centennial College where students can attend a two-year apprenticeship program called Heavy Duty Equipment Technician, which results in an Ontario College Diploma. In order to apply for the colleges heavy equipment courses, students are required to have completed at minimum an Ontario Secondary School Diploma (OSSD) or General Educational Development (GED) or equivalent. Non-academic requirements include: satisfactory results in a program admission session, experience and mechanical aptitude, resum and English proficiency.

To complete this program, students spend the first eight months in school, eight months in co-op as registered apprentices and a final eight months in school. The standout aspect of the Centennial College Heavy Duty Equipment Technician offering is that it provides a combination of business courses with a wide range of heavy equipment courses. For example, students attend Occupation Health and Safety, College Communications, Organizational Behaviour, Global Citizenship, Fixed Operations Management and more. Meanwhile, Heavy Duty Equipment courses focus on applied mechanics, vehicle dynamics as well as component design and repair, as it applies to the apprenticeship curriculum. During the in-school portion of the Heavy Duty Equipment Technician offering, students are based at Ashtonee Campus, Ontarios largest transportation training centre. This fully-equipped campus offers students the chance to fix actual heavy duty equipment vehicles using tools that are used in the field.

Once students have a base knowledge and have experienced practical practice, they spend eight months at a heavy equipment facility and then return to the college to complete their entire Ontario apprenticeship in-school curriculum in two years. The co-op experience provides the opportunity to not only apply what was learned in school but also to network and get to know professionals in the field. Many students end up staying on as full-time employees at their co-op placement upon graduation as they enter the apprenticeship aspect of their careers. The Heavy Duty Equipment Technician co-op is a paid placement.

Great Classic Car Detailing Tips For Wheels And Engine

So youve finally finished restoring the classic car of your dreams. It runs great and youre ready to take it to a car show or a cruise night.

Unfortunately, it needs to be detailed. If youve spent a lot of money restoring the car yourself, youre probably looking at detailing the car yourself as well. For some, detailing may be harder than the restoration.

However, car detailing is not as tough as you may think.

The most important thing about detailing is giving yourself enough time to do the job right. If you dont, your car will look terrible and no one will appreciate the restoration job you did.

Weve highlighted two of the most common detailing problem areas below, your wheels/tires and engine. Weve also included some tips on how to clean and polish these problem areas.

Problem Area The Engine: If youre going to a car show, you want the engine to look great. Cleaning a classic car engine is one of the more tricky detailing steps. Before you start cleaning the engine, be sure the engine is cold. You can injure yourself if you try to clean a hot engine.

When cleaning the engine be sure to take the following steps:

Be sure to cover the intake, any filters as well as the alternator.

Use a degreaser to remove grease buildup in the engine bay.

Rinse the degreaser off and use a brush to remove any excess grease and dirt.

Let the engine dry and apply and polishes and/or waxes to make the engine shine.
Following these steps will get your engine looking great for your next car show.

Problem Area The Wheels And Tires

Your classic cars wheels and tires are probably another part you want to look spotless before a car show or cruise night. People have different methods for getting great looking tires and wheels.

The most important part is finding a good tire dressing formula that will not cause sling. If youre unfamiliar with the term “sling,” its the process when the tire dressing formula splatters onto the fenders and door while driving.

If you want your car to look great, youre going to need a good tire dressing formula.

Once youve found a good tire dressing formula follow these steps:

Spray tires and wheels removing any lose dirt and brake dust.

Use a tire cleaner along with a tire brush to remove brake dust and dirt.

Rinse tires again and dry. Be sure to remove all traces of the tire cleaner.

Apply a tire dressing formula to tires. Be sure to follow directions on the bottle.
Following these steps will help make your tires and wheels look great for your next car show or cruise night.

Summary

Cleaning the engine and tires are two of the toughest areas to clean on a classic car. Following the steps above will help keep you classic car looking great.

Be sure to take care of any routine maintenance issues before taking your car to a car show or cruise night. Having an auto repair manual can help you with maintenance issues. Auto repair manuals for classic cars can walk you through various maintenance issues.

V8 engine – Home Power Inverter – Rack Mount Ups

Applications Assembled overhead valve engine with heads and complete valve train but without manifolds, rocker covers, timing chain cover or oil pan The V8 with a crossplane crankshaft (see below) is a very common configuration for large automobile engines. V8 engines are rarely less than 3.0L (183cuin) in displacement and in automobile use have gone up to and beyond 8.2L (500cuin) in production vehicles. Industrial and marine V8 engines can be much larger.

Assembled and installed with all components as seen in a rear-wheel drive vehicle V8s are generally only standard on more powerful muscle cars, pony cars, sports cars, luxury cars, pickup trucks, and SUVs. However they are often optional on vehicles which have a V6 or straight-6 as standard engine. In many cases, V6 engines were derived from V8 designs by removing two cylinders without changing the V-angle so they can be built on the same assembly lines as the V8s and installed in the same engine compartments with few modifications. Some of these employed offset crankpins driving connecting rod pairs, enabling a more regular firing sequence.

Cold Starting Devices for Diesel Engines

Attempting to start Diesel engines in cold or sub zero temperatures is extremely difficult and usually an impossible task, unless appropriate accessories has been added to the engine to assist in such starting.

The hard starting problems of diesel engines in below zero / freezing temperatures are caused by two factors. One is the initial cold air being drawn into the turbocharger and compressed into the engines cylinder head. The second is the fuel itself, is also cold and this sub zero / freezing temperature fuel is sprayed into the cold engines combustion chamber, where it mixes with the cold air drawn thru turbocharger.

Additional problems will result from fact that a cold starting diesel engine needs to reach at least two hundred (200) rpm to develop a four hundred (400) psi compression pressure to sufficiently compress the air to fuel mixture, and thus, resulting in combustion.

These two problems will result in the diesel fuel being sprayed into the combustion chamber, and it will condense on the cold surfaces of the cylinder liners or cylinder block. This liquid fuel will seep through the piston rings, and fall into the engines crankcase, diluting the lubricating oil in the process.

Two simple devices can be used to reduce the possibility that these conditions occur. One is by the use of battery heaters and glow plugs. No one device can be used. Usually a combination of several devices will provide an overall efficient starting process.

The efficiency of a battery drops as its temperature drops. A battery that is fully charged at 26 degrees C (80 degrees F) will have its starting capacity drop to approximately forty six percent (46%) available power at 17.7 degrees C below 0 (0 degrees F). Additionally, at this temperature, the engine will be approximately two and a half (2.5) times harder to start at -17.7 C (0 F) degrees due to thicker oil and resistance to movement of internal moving parts. This gets worst at lower temperatures are experienced.

To solve this, one of two common devices is used to heat the battery. One is a padded silicone covered, acid resistant rubber hot pad heater. This operates off of 110/120V and comes in various wattages. The power range can be 60W to 500W, and this can be used to heat the batteries, engine oil pan, fuel tank, hydraulic tank, and the water tank.

The other device that is typically used in conjunction with the hot pad is the glow plug. This is an internally fixed low voltage heating element that is fitted directly into the combustion chamber. When this is switched on, it can take up to two minutes to heat up, however, by that time it has reached approximately 700 degrees C (1652 degrees F) and the combustion chamber is hot enough to prevent the condensing of the diesel fuel, and thus, ignition is guaranteed.

This is to Note Motor Injection

What are the effects and the material turned motorcycle injection without waiting MIL lights on speedometers die?
At the time of ignition “ON” and the engine has not lived, then the fuel pump is already working and the fuel pump will provide the maximum pressure that the fuel will work perfectly when the machine is turned on first.

When the machine is turned on when the light is not dead MIL process that occurs at the fuel pump is not working as optimum standards (fuel pressure is still below the standard). As a result, at the start of the bike was not working at the optimum temperature (standard pressure), so that fuel consumption will be more, not direct maximum engine power and high exhaust gas emissions.

Functions and ways of working MIL lights, namely:
-To Detect early or as a marker if there is damage to Sitem PGMFI (Injection)
-To Read the damage caused to the Injection System by giving a wink to the MIL lamp.

How it works MIL lamp, are:
– If the condition PGMFI System (Injection) normal or no damage MIL lamp will illuminate when the ignition is “ON” and then will die back.
– If the condition PGMFI system (Injection) is not normal or no damage to the MIL lamp will blink, if the ignition “ON” and the MIL lamp will give you a code with a certain amount of flicker. The blinking it will give a message of damage that occurs so that riders would understand there is damage caused to the injection system.
