摘要： Methods and systems are described for combustion engine mode optimization. The system includes a combustion engine, a fuel delivery system, and a controller communicatively coupled to the combustion engine and the fuel delivery system. The controller selects a low temperature combustion mode based on the combustion engine being warmer than a predetermined temperature and low load conditions on the combustion engine. The low temperature combustion mode includes instructions that reduces an intake valve opening duration and an exhaust valve opening duration. The controller reduces the intake valve opening duration and the exhaust valve opening duration to create a delay between an intake valve opening duration and an exhaust valve opening duration in response to selecting the low temperature combustion mode. The delay increases a residual gas temperature in the combustion chamber and induces auto-ignition of fuel in the combustion chamber.

摘要： To increase the fuel efficiency and decrease the emissions of current types of internal combustion engines by improving the burning of leaner fuel mixtures, a novel igniter is provided for each combustion chamber of the engine. The igniter comprises a small external chamber into which small charges of auxiliary fuel are valved, mixed with air, and then rapidly compressed to ignition temperature by a miniature piston or ram. From each of these external chambers a small orifice leads to its corresponding engine combustion chamber. The small size of the orifice restricts the exit flow into this engine combustion chamber of the auxiliary air/fuel mixture, permitting effective compression by the rapid action of the ram. The orifice may be so shaped that the limited amount of auxiliary air/fuel mixture which passes through it prior to ignition is ultrasonically mixed and shaped in order to provide, upon ignition, a geographically desirable flame pattern in the engine combustion chamber which effectively ignites the lean main charge. The igniter compression chamber may be of small volume, e.g. 1 cc. Its piston or ram may be actuated by solenoid means with reasonable electric power consumption. Auxiliary fuel may be valved to these chambers by low-pressure electrically actuated fuel injection valves of known type. The system may be manufactured as a retrofit kit for existing engines, in which case the external compression igniter assemblies may be screwed into the spark plug holes as the spark plugs are no longer required.

摘要： Reduction of NO.sub.x emissions from a four-cycle stratified charge internal combustion piston engine is accomplished by (a) spark ignition of a rich mixture in a first chamber containing residual exhaust gas, followed by (b) torch ignition of rich mixture in a second chamber under turbulent conditions, causing (c) torch ignition of a stratified charge in a lean mixture in the main combustion chamber. The result is a reduction in peak temperature in the combustion process, with consequent reduction in NO.sub.x emissions in the engine exhaust gases. Exhaust gas is not recirculated. Said first chamber, which contains residual gas from the previous combustion cycle, contains the spark gap between spark plug electrodes and the spark gap is located near a restricted connection between the first and second chambers and remote from a closed end of the first chamber. Means are provided for changing the volume of said first chamber while the engine is operating, in accordance with variations in load on the engine.

摘要： A three-valve spark-ignition internal combustion piston engine has an auxiliary combustion chamber connected to each main combustion chamber through a torch nozzle. The intake valve for the auxiliary chamber is provided with a skirt for varying the effective size of the torch nozzle under controlled turning movement of the intake valve stem. The effective size of a restricted opening which connects the auxiliary chamber to an adjacent chamber containing the spark plug electrodes is also changed by means of a skirt on the auxiliary intake valve.
