First, let's define the term. TV stands for throttle valve, which refers to a small valve in the automatic transmission that determines hydraulic line pressure. This valve is hooked via a cable ...

Diaphragm movement induced by changes in engine vacuum actuates a lever or spring that acts on an internal hydraulic throttle valve to change the transmission's pressure. In other words ...

The hydraulic hold-open circuit automatically ... some familiar—Atkinson/Miller cycle timing, elimination of the throttle valve and its pumping losses, in-cylinder exhaust-gas recirculation ...

Digital hydraulic systems represent a marked evolution ... can be utilised to model and optimise the flow behaviour in throttle-check valves, providing critical insights into supersonic and ...

Referred to as “pumping losses,” this bottleneck caused by a partially open throttle ... does by using hydraulic fluid running through narrow passages connecting the intake valves and the ...
