Mechanical Control TRIZ Cases

A variable length connecting rod uses hydraulic fluid phase change to adjust compression ratio without active control systems.

Positioning a supercharger in front of an intercooler adjacent to the surge tank shortens air paths, reduces turbo lag, and improves throttle response.

ECU timer logic activates the low-pressure fuel pump to prevent fuel phase changes and reduce ignition delays without adding hardware.

A piston rod damper uses a second fluid chamber to absorb collision energy, preventing inertial impacts on the regulation member.

Dynamic fuel-air ratio adjustment maintains combustion stability and reduces natural gas consumption by preventing knock and misfire during low-load operation.
