Abstract
The present invention provides a system and method for controlling a two-stroke engine in correspondence with exhaust gas temperature. An engine control unit (ECU) receives an output from a temperature sensor mounted in the exhaust pipe. The engine control unit controls the operation of a fuel injector in fluid communication with the intake port of the engine in correspondence with the output from the temperature sensor. In one embodiment, correspondence is achieved by determining fuel injection parameters based on a plurality of maps, each corresponding to a different temperature range. The ECU references the map corresponding to the sensed temperature of the exhaust gas. Fuel injection parameters may include injection timing and the amount of fuel injected.
