[0005] Additionally, various ones of these systems may also require substantially steady state conditions to function efficiently. For example, in an HCCI mode, there is no sparking device to trigger the combustion event. Rather, combustion is dependent solely upon the conditions within the cylinder, i.e., temperature, pressure, air-to-fuel ratio (“AFR”), fuel state, and exhaust gas recirculation (“EGR”). These conditions are typically varied to control when auto-ignition, and consequently, combustion occurs. If there is a rapid change in
Problems solved by technology
These systems have disadvantages and are not well suited for dealing with transients, such as periods of acceleration or deceleration.
One of the disadvantages that may stem from the wide ranges and diversity of temperatures required for the spontaneous ignition of a given fuel charge (e.g. 500°-1100° F.).
This wide range of ignition temperatures combined with elevated ignition temperatures may allow a fuel charge to prematurely ignite, for example before the piston reaches top dead center, and may result in a decrease in efficiency and possible en

Abstract
Embodiments of the present invention provide a fuel supply system for combustion engines, whereby the temperatures of an oxidizer and fuel may be increased so that the temperatures approach but do not achieve an auto-ignition temperature for the fuel charge. The fuel charge may result in substantial improvements in fuel efficiency.
