Abstract
A fuel injection timing control system for diesel engines operating at high altitude includes a barometric sensor coupled to an altitude timing controller, and a throttle position sensor coupled to the engine and the altitude timing controller. The altitude timing controller adjusts fuel injection timing in response to the sensed pressure and sensed throttle position by advancing or retarding fuel injection timing by predetermined values as barometric pressure and/or throttle position changes. The predetermined values are selected to reduce exhaust emissions and/or increase engine efficiency and performance under various barometric pressure conditions so that the engine may be operated continually and optimally under various barometric conditions.
