In this study, a series of comparative experiments were conducted on a gasoline direct
ignition (GDI) turbocharged engine to investigate the effects of asynchronous intake valve …

In this study, the emissions of a TGDI engine were experimentally investigated and
compared under transient cold-start operating and steady-state operating conditions …

In catalytic gasoline particulate filter (CGPF), the higher soot oxidation rate and lower
pressure drop symbolize the good soot combustion performance. In this work, the index for …

Spark-ignited internal combustion engines are known to exhibit a decreased brake
efficiency in part-load operation. Similarly to cylinder deactivation, the x-stroke operation …

Prototype mDSF cylinder heads were based on the EA888 Gen 3B engine by retrofitting the
valvetrain with asymmetric intake cams, deactivatable roller finger followers and two oil …

Based on the self-developed hydraulic variable valve mechanism of four-cylinder engine,
this paper proposes a variable displacement valve control strategy based on the VOC-CDA …

Cylinder deactivation (CDA) is an effective technique to improve fuel economy in spark
ignition (SI) engines. This technique enhances volumetric efficiency and reduces throttling …

Variable valve actuation (VVA) technologies can provide improvements in fuel economy of
spark-ignition (SI) engines by shifting valve timings or generating valve profiles that can …

In 2020, the European parliament set the carbon dioxide (CO2) emission limit for new
passenger car fleets to 95 g CO2/km. This limit corresponds to a gasoline consumption of 4 …

Cylinder deactivation is a well-known approach to reduce the displacement of the ICE
during its operation. This helps increase specific load of active cylinders and thus improve …
