You may call it a quick and dirty manner to analyse or improve a certain engine. We believe it is better than just that, but quick it is, both from input effort as well as calculation speed.
It will enable you to generate your own engine power curve for the lap simulation, even when you have little engine knowledge. In the process, it will greatly enlarge your understanding of engines.
Valve resistance model make flow figures unnecessary
The engine model enables you to have 1 to 3 inlet valves, in combination with 1 or 2 exhaust valves, all with adjustable sizes.
The model positions the valves automatically. Out of the valve geometry the model calculate the flow curves, making it independent of flow data.
Easy to use camshaft profile generator
You have the complete freedom to specify your camshaft characteristics.
LapSim uses our own “optimal” camshaft profile generator, based on 9 parameters per camshaft.
In our view this should enable you program any 'logical' camshaft you might want to use. We decided to simplify for user-friendliness without sacrificing the accuracy.
Tune camshaft to inlet and exhaust configuration
Both the intake as the exhaust are modelled as a mass spring system, taking the inertia of intake and exhaust into account, dependent on their length and width.
The engine license will enable you to look for the best combination of individual lengths and camshaft timing.
Flexible in compression ratio, cylinder size and shape
The LapSim engine simulation has a two zone burn model, whereas the speed at which the burning continues, is a variable and dependent on the momentary temperature of the air/fuel mixture.
Hereby the model is capable of calculating the influence of compression ratio, combustion camber layout and advancing or retarding ignition.
Generated by integrating 720 degrees pressure diagram
The engine model generates a pressure diagram over the 720 degrees camshaft which is subsequently integrated to calculated the torque and power output.
The calculated engine characteristic can directly be loaded in the lap simulation.
