It's no secret that an exhaust leak negatively impacts wideband accuracy, or that it will skew readings lean, but how big of a hole would cause a significant reading change remained untested.

The idea behind Skyactiv-X is to be able to run the engine with as lean a fuel-air mixture (known as λ) as possible. Because very lean combustion is cooler than a stoichiometric reaction (where ...

White exhaust smoke usually indicates more water (or water vapor) is present than usual. If not water, then some other water-based products, like coolant, may be in the combustion chamber.

As the EPA explains, “Emissions of HAP in the exhaust gases of turbines are the result of combustion of the gaseous and liquid fuels.” HAP present in these exhaust gases include formaldehyde ...

To date, the hybrid combustion principle has been applied exclusively to the Army’s 1/4-ton M151 jeep, which is powered with a 4-cylinder engine displacing 141 cubic inches.

Motor vehicles account for an esti mated 60% of the pollutants that contaminate the nation's atmosphere. To combat this growing menace, Congress empowered Health, Education and Welfare Secretary ...

Inefficient combustion within the chamber degrades flame intensity, reducing the combustion temperature. Since exhaust gas is typically noncombustible, by recirculating metered amounts back into ...

HCCI shoots a lean mixture of gasoline, air and exhaust gas into the specially configured combustion chambers of the engine’s cylinders and then compresses it until ... produces fewer pollutants.

The fuel required in each case is directed into the combustion chamber. The mass flow of exhaust gas is discharged through the exhaust stack. Kerosene, fuel oil, natural gas and synthetic, gaseous ...

In Part 1, I regaled you all with the brief history behind the discovery of photochemical smog, and then proceeded to dazzle ...
