MAN ES reports Tier III exhaust-after-treatment orders for low-speed engines pass 1,000

Green Car Congress

Approximately one-quarter of the orders have been for EGR (Exhaust Gas Recirculation) systems, with SCR (Selective Catalytic Reduction) systems accounting for the remainder. The milestone was passed in early January 2021 and is built upon references from the company’s portfolio of ME-B, ME-C and MC-C fuel-oil engines.

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.

BP awards Colorado State University $5M to research technology for oil recovery from watered-out wells

Green Car Congress

Colorado State University has obtained a 5-year, $5-million grant from BP to study mechanisms involved with technology for oil recovery from “watered-out” wells. Typically, wells are abandoned after they are no longer producing oil or gas at a rate that is economically viable. Bill Bailey et al. 2000) Water Control.

Westport Fuel Systems & AVL conclude high-efficiency H2 powertrain can outperform fuel cells in TCO for heavy-duty applications

Green Car Congress

Hydrogen operation with the current WFS HPDI fuel system outperforms natural gas in terms of thermal efficiency, mainly due to lower equivalence ratio for H 2 at given fueling energy level, higher kinetic energy for H 2 jets as well as higher tolerance of H 2 combustion to fuel rich operation.

EV myths busted: Are electric vehicles safer than gas-powered cars?

Drive Electric

Throughout this article, we’ll refer to ICEVs and EVs; here’s a quick breakdown explaining the difference between the two. Because EVs run on electricity, the vehicle emits no exhaust from a tailpipe and does not contain the typical liquid fuel components in ICEVs. Learn more about gas vs. electric car fires here.
