The instruments were also add-ons, Mr. Wong said, helping him keep track of the turbocharger boost, engine oil temperature and the air-fuel mixture.
For modern diesel engines, variable geometry turbocharger (VGT) is used to boost engine power output.
Thermal throttling is considered as one of the rising techniques to boost engine volumetric efficiency.
Furthermore, he said, the electronics on this particular engine were tuneable, meaning that he could reprogram them to boost engine output even higher.
"We will end up with very small capacity, low rpm, highly boosted engines that have an electric motor to spin up the compressor.
The experiments were realized in a single-cylinder ported fuel injection (PFI) SI-boosted engine.
However, the boosted engine is typically designed at a lower geometric compression ratio (CR) due to the increased knock tendency in comparison to naturally aspirated engines, limiting the potential of improving fuel economy.
Then is reported the concept which leaded to the specific choice of a small displacement, high boosted engine (in terms of brake mean effective pressure) made to obtain a significant improvement of the engine global efficiency especially at partial load (if compared to most of the best competitors) and consequently a higher electric efficiency.
As an environmental friendly technology, hybrid pneumatic concept regenerating the engine braking energy to boost the engine performance for better fuel economy and lower engine emissions attracts ever increasingly attentions in automotive industry.
Traditionally, turbocharger has been an essential tool to boost the engine power, however in recent years it is seen as an enabling technology for engine downsizing.
Adaptations that boost car-engine performance are the big draw.
