There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

In the Dual Equal variable camshaft timing strategy, the intake and exhaust events are equally phase-shifted relative to the crankshaft as a function of engine operating conditions. The primary ...

The jargon goes well beyond just names. Car specs are full of abbreviations that may or may not have any meaning at first glance. And sometimes we get so used to seeing those abbreviations that we may ...

SAE International Journal of Engines, Vol. 1, No. 1 (2009), pp. 1357-1365 (9 pages) ABSTRACT From the viewpoint of protection of the global environment, reduction of CO₂ emissions are high-priority ...

Somewhere there's a perfect balance between peak horsepower, low-speed response, reduced emissions, and something you can afford. Variable valve timing and lift have done their part in getting us all ...

Despite current efforts to revisit light-vehicle fuel economy standards enacted during the Obama administration, there have been no changes to the law, and there might not be for years, as the wheels ...

The VVT system operates by advancing and retarding the cam timing to suit the speed and load of the engine. Generally speaking, advancing the cam (from 0) tends to improve low-speed power, while ...

BorgWarner has patented a variable cam timing phaser with a lock pin that acts as a shutoff valve, preventing oil leakage from advance and retard chambers. This innovation maintains oil in the phaser ...

Variable valve timing isn’t necessarily a new idea, but it is new to BMW motorcycles. With a freshly designed 1,254 cc two-cylinder flat engine, VVT is arriving in BMW bikes for the first time with an ...
