Abstract
The herein disclosed Compression Ignition By Air Injection (CIBAI) cycle and internal combustion engine has following advantages over Otto and Diesel cycles: higher thermal efficiency and operating like a stratified charge engine on lean mixtures. More reliable by lack off: spark ignition, high-pressure fuel pump and injectors; throttle valve and cold starting problems. Only one valve is required in addition to the usual I.C. engine components. However the CIBAI cycle requires one or more pairs of piston/cylinders to operate together in phase. During the compression stroke a closed cylinder-connecting valve isolates the cylinders. One cylinder compresses an air-fuel mixture to below knock level. The other cylinder compresses only air to high pressure and temperature. Near top dead center, the cylinder-connecting valve opens allowing the high-pressure air to compress, heat and ignite the pre-evaporated air-fuel mixture. This valve remains open during following power stroke and scavenging of exhaust products.
