Reduction of Fuel Consumption and Exhaust Emissions By Measurements on the Cooling System of the Otto Engine 845068
Calculating heat balance of Otto engines, one can recognize that
the ratio between heat transfer and power increases in the part
load range, i.e. city driving. To improve the efficiency of such
engines it is necessary to reduce the quantity of heat transfer and
also of friction losses. Both effects can be achieved by increasing
the temperatures of the cooling medium and the lubricant. This
leads to two effects: - reduction of fuel consumption - reduction
of exhaust emissions.
Both effects are valid even in the warming-up-phase as well as
under normal operating temperature and are confirmed by the results
of our experiments.
