SAE Transactions, Vol. 106, Section 3: JOURNAL OF ENGINES (1997), pp. 848-860 (13 pages) Multidimensional modeling is used to study air-fuel mixing in a direct-injection spark-ignition engine.

Electronic fuel injection is better for its efficiency, but installing it in a car that wasn't built for it requires ...

ABSTRACT Non-conventional operating conditions and fuels in diesel engines can produce longer ignition delays compared to conventional diesel combustion. If those extended delays are longer than the ...

Ford Motor has patented a method for adjusting injection timing of closely spaced multiple injections using the same injector. The system adjusts timing based on previous injections, optimizing fuel ...

Ignition timing is easily the single most important tuning adjustment on an internal combustion engine and yet the concept of ignition curves continues to be elusive for many enthusiasts. Yet all it ...

Ignition timing is typically split into three types. The first is initial timing—that is, the amount of spark lead that is set using a timing light (aimed at the harmonic balancer) with the engine at ...

"It's not a heap, dad. It's a classic." That's harder to justify when your classic muscle car won't start. Nothing like a high-compression V8 combined with a battery that hasn't seen a charge for a ...

Welcome back for Part 2 of tune-up tips for your older Corvette. Last time we talked about tricks of the trade when setting points. This month we will talk about setting ignition timing. The most ...
