Homogenous Charge Compression Ignition Engine

  • HCCI is an hybrid engine technology, which combines the advantages of Spark Ignition (SI) Engines and Compression Ignition (CI) Engines.

  • It provides efficiency as high as CI Engines and Ultra-low NOx and PM emissions.

  • The charge inducted in the cylinder is homogenous which burns volumetrically throughout the combustion chamber simultaneously, thus reducing PM emissions however the combustion temperature is also comparatively lower, therefore NOx formation is also highly reduced.

  • This is a two cylinder, constant speed, 4 stroke, air cooled, direct injection diesel engine. One out of the two cylinders is modified to run on HCCI mode, while the other cylinder runs on conventional diesel combustion mode.

  • A dedicated device is used as diesel vaporizer for vaporization of diesel, which helps in homogenous mixture formation. The fuel is injected in the cylinder using port fuel injection.

  • Start of combustion is being controlled by Exhaust Gas Recirculation (EGR). EGR dilutes the mixture in the cylinder and reduces the oxygen content and in turn controls the start of combustion inside the combustion chamber.

  • High speed data acquisition system is used to acquire data from the engine. It allows simultaneous monitoring, processing and recording of various data sets from the engine.

Automotive industry is striving hard to reduce fuel consumption in engines, increase efficiency and reduces emissions from the engines, and the HCCI engine technology holds the potential to combat these problems.

This technology stands out as a strong candidate for future automotive engines, which will have high fuel efficiency, and produce lower emissions. The experiments can be performed with various fuels such as diesel, biodiesel and gasoline.
