Generally, a compact diesel engine equipped with a turbocharger can obtain higher mean effective pressure and higher power. For such engines, the power and rotational speed of the turbocharger cannot match sudden increases in engine load. In this case, engine stall occurs resulting in poor combustion and increased smoke. A jet assist system installed on the compressor casing can effectively reduce turbocharger lag. This jet assist system is useful to improve the acceleration performance of the turbocharger. Therefore, the application of a jet assist system in turbocharged engines prevents engine stalls and reduces smoke.
This paper describes the design approach and test results of a turbocharger equipped with a jet assist system.
