Auto Parts Manufacturers Create ‘SERVICE-EDU’ Training Program
SERVICE-EDU is a new training program for professional automotive service and repair technicians from four premier OE automotive parts manufacturers: Gates, MAHLE, NGK Spark Plugs and Timken. Training will be held at regional Universal Technical Institute (UTI) campus locations across the United States.
Engine Bearings Under Pressure
Engine bearings have to withstand punishing loads in today’s engines. Smaller displacements, turbocharging and higher horsepower ratings mean crankshaft and connecting rod bearings are being subjected to heavier loads. This has led to the development of some new bearing alloys and coatings that enable these parts to survive.
How Oil Change Habits Are Killing Turbos
Turbochargers are used to enhance an engine’s performance and optimize combustion. To achieve good and complete combustion in the engine, a mixture ratio of 2.2 lbs. fuel and approximately 33 lbs. air is necessary (stoichiometric fuel ratio). During turbocharging, the density of the intake air is elevated and the air volume increased.
Diesel Performance Head Gaskets
Head gaskets have a tough job sealing combustion pressures in diesel engines because of their high compression ratios and boost pressures. Diesel engines are typically low revving, high torque motors that are designed to last several hundred thousand miles.
Follow the Money: How Money is Raised for SEMA Scholarships
An important means for raising money for the SEMA Memorial Scholarship Fund has been the annual auctioning of an engine on eBay. This engine is built entirely of aftermarket components manufactured by SEMA member companies.
Under the Hood: Diesel Dialog- Talking ‘Bout Performance Diesel Pistons
The interest in diesel performance has been growing. Bolt-on performance packages for diesel-powered pickup trucks can easily add 75-150 horsepower or more for everyday driving and towing. While pulling has been the traditional use for diesel-powered tractors and trucks, diesel-powered vehicles are now winning races and setting records in venues that have long been the exclusive realm of gasoline-powered engines.
