Builders are ready to sell you new trucks that should prove to be reliable and economical. But if you'd rather wait and see how the EGR'd diesels work out, there's probably plenty of life left in what ...

The spray development, combustion and emissions in a 1.9L optical, four-cylinder, direct-injection diesel engine were investigated by means of pressure analysis, high-speed cinematography, the ...

Q: I have a 1990 Toyota Corolla LE, with automatic transmission, which I purchased new. It now has 101,000 miles on it. In all the years I’ve had it, there was never a major problem. All the service ...

ABSTRACT Numerical simulations of a heavy-duty diesel engine fuelled with n-heptane have been performed with the conditional moment closure (CMC) combustion model and an embedded two-equation soot ...

A mechanic who was doing a repair on a Dodge Ram found an unexpected problem that caused a whole new level of alarm for him. The video documenting the situation comes from Dave’s Auto Center ...

I have a 2009 Peugeot 3008, 1.6 HDI with 110,000 miles recorded. I have owned it for three months. Recently the engine light has come on several times, and gone off again, and then came on permanently ...

Most modern gasoline and diesel-powered engines found in the cars and trucks seen on today's roadways rely on the four-cycle-engine principles developed in the late 1800s by Nikolaus Otto, Gottlieb ...
