Abstract
Apparatus and method for compensating fuel delivery to the cylinders of internal combustion engines for the barometric pressure; for the intake air temperature; and for the heat transferred from the internal engine surfaces to the intake air prior to the air being confined within the cylinder. In the apparatus, temperature sensors are placed to measure internal engine surfaces. The method and apparatus can be used with both a four-stroke or two-stroke engine. In a two-stroke engine, the sensor would be mounted on the crankcase; in a four-stroke, on the intake manifold.
