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.

Increased efficiency in all of the new Ecotec engines is achieved in part through lower engine friction, which was reduced by up to 16% using new technologies such as a variable-displacement oil pump. Rotocast aluminum cylinder head with sodium-filled exhaust valves. Forged steel crankshaft. Pistons with jet-spray cooling.

two-stroke main-engines that feature integrated Exhaust Gas Recirculation (EGR) systems. EGR is a NO x emissions-control technology that works by recirculating a portion of an engine’s exhaust gas back to the engine cylinders. Sodium hydroxide dosing is therefore required to neutralise the acidic scrubber water.

By conducting more heat away from the valve head, the new seat materials reduce the temperature in the hottest part of the combustion chamber and lower the gas temperature at the end of the compression stroke: improving knock resistance and allowing a wider range of ignition advance to enable optimisation of combustion.

The market will receive a boost from new diesel locomotive emissions regulations scheduled to go into effect in the European Union in 2014 and in North America in 2015, which will require diesel locomotives to receive substantial changes or exhaust treatments. —senior analyst Dave Hurst. —Dave Hurst.

liter turbocharged I-4 engine is part of the Global Medium Engine architecture family and features Double Overhead Camshafts (DOHC), dual independent camshaft timing, and a cooled exhaust gas recirculation (C-EGR) system. An inverted tooth primary chain drives both the intake and exhaust camshafts and minimizes noise.
