Performance Pistons

This month we’re going to take a look at the various technical aspects of pistons designed for performance and competition engines. If we consider the extreme environment of combustion pressures and high temperatures that regular cast replacement pistons operate in, it’s quickly apparent that when these values are increased it Read more…

Selective Catalytic Reduction?

The Diesel Technology Forum recently issued the following explanation on Selective Catalytic Reduction (SCR), an advanced active emissions control technology system used in clean diesel engines. Selective Catalytic Reduction (SCR) is a proven and advanced active emissions control technology system that injects a liquid-reductant agent through a special catalyst into the exhaust stream Read more…

Complexities of Modern Timing

Let’s face it: timing used to be relatively easy. These days, however, as with most every other engine component, the technology and innovation that leads to more fuel efficiency and performance also means increased complexity with timing components. You’re already facing challenges in understanding late model chain drive timing systems Read more…

Building for Biodiesel

Some people have a negative view of biodiesel. They say it gums up the fuel pump and injectors. They say it gels in cold weather. They say it’s diverting food resources to make fuel. They say it’s too expensive and can’t compete economically with conventional No. 2 diesel fuel. Then Read more…

Pushrod Failures

1. What are the biggest challenges that face today’s competition pushrod maker? “Racers seeking to exploit every tiny advantage tend to select lighter and lighter weight oils, many of which are impaired or even deficient in lubricity at high loads and high revs. Also, installing pushrods positioned between lifters and Read more…
