Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

A large body of work shows that exposure to road traffic and air pollution may be a trigger of adverse cardiovascular events such as angina, myocardial infarction, and heart failure, with long-term exposure increasing the lifetime risk of death from coronary heart disease.

Researchers show mechanism by which diesel exhaust particles trigger respiratory “flare-ups”

Green Car Congress

Researchers at Imperial College London, working with colleagues from King’s College London and University of British Columbia, have demonstrated a mechanism by which diesel exhaust particles directly affect the lungs to initiate symptoms such as a tightening of the airways and cough.

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

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. Source: Borgwarner. Click to enlarge.

Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

With SCR twin dosing technology in the exhaust gas system, the diesel unit now undercuts the Euro 6d emission standard limits while also running quietly and smoothly, according to the company. Despite the severe business and political ramifications of the event, Volkswagen persevered with its diesel engine development, and in 2018, the 2.0L

Cummins & Tula demonstrate Diesel Dynamic Skip Fire (dDSF) cylinder deactivation; up to 66% reduction in NOx on CARB LLC #7

Green Car Congress

dDSF improves fuel efficiency by firing all events at the most efficient ratio of air to fuel, allowing optimal combustion at all engine output levels. The reduction of tailpipe NO x is achieved primarily by optimized exhaust temperature control, resulting in significantly improved conversion efficiency of the aftertreatment system.
