Everything You Want To Know About Engine Efficiency
BG Engine Efficiency Concentrate offers critical protection for small engines. Developed specifically for fuel-injected Harley-Davidson® motorcycles, Screamin’ Eagle® EFI Stage Kits supply complete street-legal and racing performance configurations engineered to help you generate specific torque and horsepower good points at a given engine calibration.
Eliminating all the guesswork and trial-and-error testing usually related to engine modifications, Stage Kits embrace every thing you must enhance your bike’s performance, together with massive-bore cylinders, excessive-compression pistons, performance cams and excessive-movement air cleaners.
This is achieved by putting extra air/fuel combination into the engine, increasing compression ratio (requires higher octane fuel) burning it more rapidly, and eliminating the waste products more quickly – this increases volumetric effectivity In an effort to test the amount of the air/gas mixture, air fuel ratio meters are often used.
Outcomes of the engine test indicated that using ethanol-gasoline blended fuels, torque output and fuel consumption of the engine barely increase; CO and HC emissions lower dramatically on account of the leaning effect attributable to the ethanol addition; and CO2 emission will increase due to the improved combustion.
Raising the compression ratio by decreasing the scale of the combustion chamber, which makes more efficient use of the cylinder stress developed and resulting in extra speedy burning of gas, by utilizing bigger compression peak pistons or thinner head gaskets , or through the use of a milling machine or “shaving” the cylinder head Excessive compression ratios can cause engine knock until excessive octane fuels are used.
