New VW Golf now available to order with natural gas drive

Green Car Congress

The tanks are integrated into the underbody and permit a range of around 400 kilometers (WLTP) in pure natural gas mode. The engine of the quasi-monovalent drive system is powered primarily with CNG (Compressed Natural Gas), but can also run on gasoline. Driving in CNG mode produces around 25% fewer carbon emissions than with gasoline.

Chalmers study: ban on sales of fossil-fuel cars greatly reduces lifecycle GHG mainly due to tailpipe emissions; risk of carbon leakage in manufacturing

Green Car Congress

If a ban were introduced on the sale of new gasoline and diesel cars, and they were replaced by electric cars, the result would be a significant reduction in lifecycle carbon dioxide emissions primarily due to reduced tailpipe CO 2 emissions, according to a new lifecycle study by researchers at Chalmers University of Technology, Sweden.

New Pierburg air blower with speed-controlled motor for reduction of gasoline engine emissions

Green Car Congress

Secondary air systems are used to reduce gasoline engine emissions by accelerating catalytic converter heat-up. The latter allows secondary air injection across a much wider engine map range and hence, at any given point in time, the precise air mass required for accelerating converter heat-up is injected into the exhaust system.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.
