Turbocharging and downsizing can also yield fuel consumption reductions. Downsizing is an important strategy applicable in combination with technologies that increase engine torque, such as turbocharging or supercharging. Part of the gain from advanced-level CI diesel engines comes from downsizing.

Many countries propose to impose more stringent regulation of automobile exhaust emissions in 2020 and after, in an effort to prevent air pollution and global warming. TDK offers a lineup of products, such as DC-DC converters, on board chargers and wireless power transfer systems that are currently being developed.

The automotive industry, including Lotus Engineering, has quite rightly advocated engine downsizing for four-stroke engines. The two-stroke cycle, conversely, does not suffer from significant throttling losses and in many ways is a more natural fit for automotive use. Displacement. Compression ratio. Porting arrangement.

Conversion to wider gear ranges. Shift responsiveness has improved through downsizing of the pulley and reduction of inertia by 40%. It also achieves greater thermal efficiency, resulting in high output, due to a reduction in energy loss associated with exhaust and cooling systems, the movement of mechanical parts, and other aspects.

Conversion efficiency is now the key. A sole single-stage compressor and single-stage exhaust turbine are used for pressure charging. Unlike previously where two exhaust tailpipes were used, the 2014 regulations mandate the use of a single, central exit tailpipe through which all exhaust gases must pass. The F1 W05.

Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Because the intake and exhaust ports are at the opposite ends of the cylinder, opposed-piston engines have efficient, uniflow scavenging. Scavenging continues until a 230° crank angle, at which time the exhaust ports close.

The Scuderi engine divides the four strokes of a combustion cycle among two paired cylinders—the left cylinder functions as an air compressor, handling intake and compression, while the right cylinder handles combustion and exhaust.

Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine.
