Combustion Engines TRIZ Cases

This case shows how a slow-rotating, centreless flexible auger transports sludge and oil, reducing manual cleaning and engine disruption.

A stratified scavenging two-stroke engine uses segmented passages to supply leading air for effective exhaust gas removal.

Merging separate compressor and pump units into a single assembly eliminates undercarriage clutter by transferring rotary motion via a common shaft.

A rotary carburetor nozzle tube uses a guide plate member to direct discharged fuel into the engine intake system mixture passage.

A two-stroke engine uses a dedicated charge piston to compress air and separate lubrication from fuel combustion.

Zinc alloy inserts in flat tubes form sacrificial anodes that prevent corrosion while boosting heat transfer efficiency.

An elastic spring washer decouples the injection valve from the cylinder head, absorbing momentum to minimize solid-borne noise emissions.

A power generation system uses a reciprocal heat-insulating cylinder to convert thermal energy into kinetic energy via phase transitions of the operating fluid.

Segmented compression chambers with self-service valves supply continuous compressed air to the combustion chamber, reducing oil consumption.

Rotating nebulizing members atomize fuel and water mixtures while magnets remove ferromagnetic impurities to reduce pollutant emissions.
