Secondly, the expansion cylinder can operate at near adiabatic conditions and at a different expansion ratio to the compression cylinder compression ratio in a split cycle engine, without the pumping losses incurred in an Otto or Diesel cycle engine [14].
The conduction of tests in engines of agricultural machines with Diesel cycle is the most common, such as the consumption in sugarcane harvesters evaluated by Ramos et al.
The Diesel cycle engines used in tractors present three types of fuel injection system, although there are others, which are individual pump, rotary pump and system with a complete injector unit (MIALHE, 1980).
The ideal Stirling cycle is unattainable in the real world, as with any heat engine; efficiencies of 50% have been reached, [4] similar to the maximum figure for Diesel cycle engines.
The data were collected by performing dynamometric tests using two engines for the same John Deere agricultural tractor (model 6415), equipped with used John Deere diesel cycle engine (model 4045T, series 350), turbocharged with direct injection four cylinder and 4.
Instead of premixing the fuel and air, "they were operating on a diesel cycle, in which air is compressed and fuel is injected," he said.
Among the proposals of alternative fuels, the addition of ethanol in diesel oil has gained attention, being its use in diesel cycle engines stimulated (HANSEN et al.
Because we retain the diesel cycle, we'll have a very high power density in relation to other natural gas engines on the market," according to Doug Yip, director of Westport's high horsepower group.
Tests at the Colorado Institute for Fuels and High Altitude Engine Research also confirmed that Westport's system on a 6V-92TA engine maintained diesel cycle thermal efficiencies while reducing emissions of nitrogen oxides by 37 percent and particulate matter by roughly 70 percent.
