Turbo Discharging



Turbo-discharging is a key new technology available to the IC engine power generation industry that can offer performance and fuel economy improvements for gas, petrol and diesel fuelled engines.

Turbo-Discharging is an additive technology in that the benefits it offers are mostly independent of existing and future fuel efficiency technologies. It can offer benefits to future engines including turbocharged (TC) and naturally aspirated (NA) gasoline engines, diesel engines, gas engines, rotary engines, of any fuel type, hybrids and those with exhaust heat recovery systems.

The amount of benefit from turbo-discharging is a function of the exhaust gas temperatures, load control (e.g. fuelling or throttling) and engine characteristics. The table below indicates the relative fuel economy, torque and transient response benefits for different common engines. Engine test data has demonstrated up to 6% fuel economy benefit and more than 7% torque increase across a significant region of the operating range of NA gasoline engines. Simulation on turbocharged engines indicates significant low speed torque benefits, potential improvements in transient response in addition to the fuel economy benefit.

Turbo-discharging is not dependent on development of new and costly materials or components and can therefore be rapidly implemented with a very good cost-benefit ratio.
