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.

Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Before they can be used, however, it is essential to understand their physical properties, combustion chemistry, and characterization of the exhaust due to a number of issues associated with fuel properties—for example, a lower heating value and higher cloud point than regular diesel. Kumar et al.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

In cooperation with a major European supplier, a new oil-lubricated common-rail pump had therefore been developed. An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption.

Nonthermal plasma torch reforming of exhaust gas for NOx trap regeneration

Green Car Congress

Researchers from the Center for Energy and Processes (CEP), MINES ParisTec, and Renault are exploring the non-catalytic reforming of diesel fuel with diesel engine exhaust gas (i.e. An alternative to the catalytic exhaust gas reforming of diesel fuel method is presented in this paper and consists of using an NTP torch. trap catalyst.

Achates near-zero heavy-duty opposed-piston diesel enters fleet service; compliant with 2027 NOx levels

Green Car Congress

The cleaner engine is able to deliver ultra-low NO x by managing exhaust gas temperatures to ensure rapid catalyst light-off and by maintaining aftertreatment temperatures at optimum operating conditions in all driving conditions.

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. It is very basic research at the simplest chemical level.
