New Automotive Engines

3.8 L automotive engine

The new automotive engines on the market today have gone through a lot of changes compared to engines installed just a decade ago.

This new wave of engines is designed to meet the performance and fuel efficiency that the public demands.

It is clear if the automotive manufacturer does not come up with a strong power train that impresses all who drives it their sales will begin to sag and possibly never recover.

This is mostly due to the word-of-mouth from disappointed drivers. The power of this viral negativity is truly amazing.

Example: My father had a bad experience with a Ford Pinto. He told everybody that would listen about all the troubles he ever had with this car.

Right off the showroom floor this car would use a quart of oil a week. The pistons and rings had to be replaced under the old-fashioned 12/12 warranties. The hard part was getting the dealership to admit a problem existed.

It took much fighting with Ford Motor Company and the local dealer about what normal oil usage should be.

Every Christmas and thanksgiving our large family sat around listening to details of the battle for justice. The results are that nobody in my family or circle of friends has ever bought a Ford product since my dad’s bad experience in the mid-70s. Talk about holding a grudge!

Modern automotive engines are made of lightweight engine castings, and in most cases non-iron materials.

Some of the types would include aluminum, magnesium carbon fiber materials, and in some cases reinforced plastics.

If the block is made out of aluminum the use of a stainless steel cylinder liner is used most often.

When it comes time to assemble the engine, fasteners that hold things together are now fewer and smaller than ever before.

This is made possible through computerized engine design (CAD, CAM) that optimizes the loading and sealing patterns when the motor parts are assembled. Read more
