MAN Diesel & Turbo has announced that its turbocharger technology has passed a significant milestone. The company is celebrating the 1,000th delivery of its turbocharger to two-stage turbocharged applications.
The MAN ECOCHARGE solution was developed in late-2000. It combines low and high pressure stages with intercooling to significantly improve engine performance. The technology increases turbocharging efficiency compared with single-stage and high-pressure stage turbochargers, significantly reducing energy that is required to compress intake air to high pressure. This means that the air pressure over the cylinder is increased during the scavenging process.
Nitrogen oxides (NOx) reduction is also achieved as greater turbocharging efficiency reduces the formation of NOx via the Miller cycle, while improved scavenging efficiency from the ECOCHARGE technology allows for choice between boosting engine power output or reducing engine size. With a smaller engine, ECOCHARGE can give the same output power of a larger engine thanks to its increased efficiencies and higher cylinder rating facility. To date, MAN ECOCAHRGE has been applied to several new four-stroke engines types that can also operate on gas.
Ragnar Olafsson, Head of Sales OEM Applications Turbocharger, MAN Diesel & Turbo commented: “Besides our core company business that covers marine and power applications, we also deliver a large number of our turbochargers to other engine builders throughout the world. Through our OEM business, we have gained a great deal of experience in applications that are atypical for MAN Diesel & Turbo, such as mechanical drives, locomotives or mining”.
