Under Pressure: Part 1 of the diesel injection evolution

Two of the largest gains of diesel injection development throughout the years have been electronic control and higher injection pressures. The greater the injection pressure, the more finely both the injector and injection nozzle will be constructed giving a droplet less gas like injection mixture. This improves atomisation and results in a better air-fuel mixture, […]

How to Protect Your Engine with Filtration in the Truck and Mobile Aftermarket

Regardless of how much care is imparted, fuel contamination such as dirt or water will always find its way into any fuel system. Unfortunately, because the latest diesel engines offer fuel injection pressures exceeding 2000 bar along with micron-level injector tolerances, even the tiniest amount of dirt or water is certain to create problems. In high-pressure […]

GDi-What does it mean

Gasoline direct injection (GDI) is a fuel delivery system in gasoline internal combustion engines. The system represents the very latest technology in fuel injection. It utilises a high-pressure common rail accumulator assembly which injects the fuel mixture directly into the engine’s combustion chambers. GDI systems also gives improved fuel efficiency, higher output power values, no throttle losses, and […]

Some Euro 6 diesel cars are FAILING roadside emissions tests

Article written by Ethan Jupp, MR (Motoring Research) A Driver and Vehicle Standards Agency (DVSA) report suggests a high risk of modern cars failing emissions tests at the side of the road in ultra-low emissions zones (ULEZ), potentially meaning that they shouldn’t be granted ‘free’ access. The issue has been highlighted by Allow Independent Road-testing […]
