Valve train improvements are an important part of the continued efficiency advancements of internal combustion engines. Today's electronics allow more precise control and different approaches to valve ...

The valve train is probably one of the most complex and critical assemblies in a modern automobile engine. Its operation directly impacts engine efficiency and emissions. Engineers with the General ...

With the short block assembled for our 383 supercharged project motor, it's time to shift our attention once again; this time to the heads and valvetrain. Like the rotating assembly, when it came to ...

Scientists have developed an innovative, electrohydraulically actuated valve train for internal combustion engines, that enables completely free adjustment of stroke and timing, while at the same time ...

Engineers at DaimlerChrysler once analyzed valve trains with nothing more than old Fortran programs. But 3D dynamic-simulation software now handles the task with features tailor-made for modeling fast ...

How much power can you get from forced induction? Under optimum conditions you can experience as much as a 50 percent increase. However, this is the real world and your numbers are likely to be less.

The UK inventors of an innovative valve-train technology which dispenses with the traditional camshaft claim it could radically improve petrol engine performance. Jon Excell reports Major leaps in ...

It’s true, nothing lasts forever and all good things tend to have a cycle. In this instance, we’re talking about the lifespan of your cylinder head’s valvetrain. Obviously a lot of this is contingent ...

QUESTION: I have a 2006 Honda Accord four-cylinder with 105,000 miles. It has developed a clicking engine noise on a cold start. After the car has warmed up, the sound goes away. I have seen ...
