The Rochester Ramjet is an automotive fuel injection system developed by the Rochester Products Division of General Motors and first offered as a high-performance option on the Corvette and GM passenger cars in It was discontinued partway through in favor of the Chevrolet Big Block as a performance option. In the early s, fuel injection was the topic of a significant amount of research by the auto industry in the US and internationally. Ed Cole , who had become the chief engineer of Chevrolet in , pushed for Chevrolet to be the first GM brand to offer a fuel injection option on a production car. Dynamometer-based tests of a cid small block engine running with fuel injection were performed as early as

In this paper, the potential of combined injection of CNG and gasoline is studied on a 1. Compressed natural gas CNG as an alternative fuel is used in spark ignition engines to improve fuel consumption and exhaust emissions. The improvements gave more advantage in emission but it lowered the performance of the engine. As a substitute, CNG has a higher octane number and knocking resistance than gasoline and hence CNG-dedicated engines can have higher compression ratios and therefore higher indicated efficiencies. Turbocharged bi-fuel, combined CNG and gasoline, injection engine of is a new concept which offers direct benefits with regards to gas or gasoline powered vehicles running separately on each fuels.
