A method and apparatus are disclosed for controlling the rate and timing of heat released during each combustion cycle of an internal combustion engine so as to maximize the net work output of the engine. Mathematical expressions of engine loss factors, such as friction and heat transfer, are used to establish a combustion chamber pressure versus crank angle function which is analyzed together with a combustion chamber pressure versus crank angle function in the absence of combustion. From this analysis, a derivation of optimized combustion chamber heat release rate and timing is enabled. The optimized combustion chamber heat release rate and timing are achieved by controlling the timing and rate of injection of fuel into the combustion chamber, which fuel has been activated by pretreatment so to enable "hypergolic" or instantaneous combustion upon injection.
