BorgWarner launches new low-friction engine timing chain; 0.3-0.6% improvement in fuel economy

Green Car Congress

improvement in fuel economy based on customer testing. As automakers began downsizing engines to improve fuel economy, BorgWarner recognized opportunities to help further improve engine efficiency by reducing power-wasting friction in the engine timing system.

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

Turbo boost can be controlled by changing the timing of the exhaust valves—no waste gate is required. In testing, BorgWarner observed fuel consumption improvements of 2% at low speeds to 12% at high speeds with VEMB, according to Thomas. improvement in fuel economy on an E-class vehicle (e.g., Source: Borgwarner.

McMaster team reviews progress on hybrid-specific engine technologies

Green Car Congress

A team from McMaster University in Canada has published a comprehensive review of recent progress in low-temperature combustion (LTC), alternative fuels (AF), over-expansion Atkinson cycle, and waste heat recovery (WHR) techniques as applied to hybrid-specific engines. Their open-access paper is published in the journal Energy Reports.

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

The analysis used the Ohio State University EcoCAR, a student prototype PHEV, as the basis for the preliminary fuel economy evaluation. This evolution has led to the point where achieving significant fuel savings through the introduction of new technologies has become difficult. —Skarke et al.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

A paper on their work is published in the ACS journal Energy & Fuels. Blending 25-50% of this low-temperature ethanol reformate with ethanol or E85 fuels enables dilute engine operation, resulting in substantial improvements in fuel economy and emissions. —Sall et al.
