The measurement conditions of exhaust gas temperature
in the mode of WMTC are as follows.
The result for exhaust gas temperatures
versus with the engine speed is shown in Figure 4.
This is complicated by the thermal lag in the vehicle's exhaust system causing a delay between a change in injection quantity and the resulting change in the exhaust gas temperature
Exhaust gas temperature
increases with EGR for both compression ratios due to slower combustion, in particular, in the later part of it.
The performance, combustion and emission parameters like brake thermal efficiency, specific fuel consumption, volumetric efficiency, P-[theta] curves, instantaneous heat release, cumulative heat release, exhaust gas temperatures
, CO, C[O.
This arrangement, part of International's proprietary Eco-Therm heat-management system, is engineered to control coolant flow and temperature across the various coolers to achieve optimal intake air and exhaust gas temperatures
under all conditions.
These improvements lower operating temperatures, increase exhaust gas temperature
margin, and increase engine time on wing while retaining the demonstrated CF6 stall-free reliability.
At an appropriate level of trap 611, a controlled richening of the air/fuel ratio (to a substoichiometric value) produces a combination of a high exhaust gas temperature
and a stream of CO and unburned hydrocarbons which enables the catalyst to regenerate, thereby converting the stored [NO.
By incorporating 3-D aero in the engine's turbomachinery, the CFM56-3 gains an additional 15 degrees centigrade in exhaust gas temperature
By further developing this injection system, Hino is now able to control the injection pattern and raise the DPF temperature for a short time, even when the exhaust gas temperature
6 percent fuel burn reduction and over 20 degrees Celsius increased exhaust gas temperature
A wide range of other conditions, including coolant level, fuel pressure, coolant pressure, oil level, oil and fuel temperature, intercooler temperature, percent throttle, fuel rate, boost pressure, manifold temperature, air filter differential pressure, exhaust gas temperature
, ECM battery voltage, air inlet temperature and injector pressure, can also be monitored and displayed.
