Time was when a valve job was done with some valve-grinding compound and a vacuum cup on a stick. But no more. Today's high performance engines require the same machining precision in the valves that ...

While the engineering community continues to explore the benefits of electric and hybrid vehicles—i.e., the environmental and renewable energy factors—the automotive market is still dependent on ...

Does your engine need a valve adjustment? It depends on the age, condition and brand of vehicle you’re driving. Due to the popularization of roller-follower valve train designs that reduce friction ...

Prototype IVA engine swaps a usual longitudinal camshaft for short, individually driven camshafts sited across the top of the cylinder head. IVA cam drive is by ECU-controlled electro-mechanical ...

The language of import performance can be strange. Sometimes it's a verbal stew of numbers and letters--RX-8, NSX, and MR2, for example--that seem randomly tossed together. At other times it adopts ...

Kurt Ernst February 20, 2013 Comment Now! As advanced as internal combustion piston engines have become over the past few decades, they’re still hampered by a few basic design limitations. Chief among ...

Modern engines contain hundreds – nay – likely thousands of different parts. There are valves and springs, at least one camshaft, engines also have bearing inserts, an oil pump, numerous gaskets, ...

Learning how to build and understand a mini engine is an exciting journey for anyone interested in mechanics. A mini engine, despite its small size, works on the same principles as larger engines. By ...

GM has filed a patent application for a two-stroke engine valve system. The patent application is tagged with patent number US 2025/0354528 A1 and was filed with the United States Patent and Trademark ...

Taking care of your vehicle is vital to ensure it stays in great condition. Your brakes could give you trouble someday, or your suspension could require tinkering, inevitably leading you to an auto ...
