In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

In cooperation with a major European supplier, a new oil-lubricated common-rail pump had therefore been developed. An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption.

Lubricating oil is usually used in pumps to reduce stress through less friction in the pump; however, lubricating oil cannot be used in liquid hydrogen pumps as it contaminates the hydrogen. This reduces engine oil dilution and improves reliability and exhaust performance by reducing the burden on the engine.

Known internally and to Volkswagen enthusiasts as the “Evo4,” its two most difficult roles might be under the hood of the 2022 Golf GTI and R. To keep things cool under pressure, switchable piston oil jets activate under high load conditions. The 2022 Golf GTI makes 241 horsepower and delivers an EPA-estimated 34 mpg on the highway.

To comply with Euro VI the Cursor 9 CNG does not need Exhaust Gas Recirculation (EGR) or Selective Catalytic Reduction (SCR), but relies on a simple three-way catalyst. Compared to the Cursor 9 diesel, the new engine has a Ni-Resist cast-iron exhaust manifold and water cooled wastegate turbocharger, increasing reliability.

Toyota introduced the next-generation three-row 2020 Highlander SUV at the New York International Auto Show. The gas engine employs Variable Valve Timing-intelligent system by Electric motor (VVT-iE) on the intake camshaft, and VVT-i on the exhaust camshaft.
