In the past two months we've covered most of the emission systems that have appeared on recent automobiles. This month we'll conclude our discussion of these systems with those devices designed to ...

When the auto manufacturers first introduced their newfangled multiport fuel-injection systems, many hot rodders feared that the days of performance tuning and tweaking were gone. However, nothing was ...

This paper describes a new stratified-charge combustion system called the Mitsubishi Combustion Process (MCP), accomplished by controlling the air swirl and improving the injection nozzle in ...

I’m hoping you can bring an old-timer up to speed on fuel injection. I used to be pretty good at fixing things but hadn’t even considered trying to work on this one. I’d feel better driving if I had ...

Injecting water and/or methanol into a diesel engine (gas, too) has been around for more than 75 years, but it didn't really have a good, practical application until WWII, when supercharged and ...

NOx emissions can be controlled through engine operation with lean homogeneous air/fuel mixtures. This emission control approach precludes the need for exhaust gas recirculation (EGR) and secondary ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...

Garrett Motion. has filed a patent for methods and systems utilizing model-based calculations to control mass flow in internal combustion engines. The system includes a secondary air injection valve ...
