AVL had a pretty good day earlier this month, when it confirmed its prototype 2.0-liter turbo hydrogen race engine could generate over 200 hp-per-liter. AVL uses a water-injection system alongside ...

Running lean for too long under these conditions can cause engines to run hotter, making it much more likely for you to burn valves, crack pistons, or warp cylinder heads.

It's one thing for a car to run on air, but do the latest claims of hydrogen-turned-oxygen-turned-electricity propulsion hold wateror feed in to the hysteria of the gas crunch?

I have a megasquirt FI on my 1964 VW bus, 1776cc engine. I lean burn approx 16:1 at hiway cruise 60mph. Ignition advance is 40 degrees. Mileage is about 28mpg.

Electronic ignitions call for large gap, and lean-burn engines may not color the porcelain at all. This might be a tad lean, but there's no indication of overheating or detonation. See All 15 Photos ...

It’s “a theoretical combustion method,” according to this document, that “achieves high thermal efficiency by realizing super lean burn combustion over a wider range from low to high rpm ...

So as far as your high-performance engine is concerned, forget the old F3 and F4 (lean and rich) numbers; use them to identify the fuel. It's enough to know that octane numbers for Av-Gas in your ...

The patent US12044192B2 presents a novel air intake port designed specifically for lean-burn gasoline engines. The air intake port features an air inlet, two air outlets, and an air channel that ...

Built around a small, lean-burning four-cylinder engine, the HSD was effectively an electrical accumulator, harvesting and releasing energy otherwise lost in coasting or braking.

Running lean for too long under these conditions can cause engines to run hotter, making it much more likely for you to burn valves, crack pistons, or warp cylinder heads.
