## Typedefs
typedef struct SDTMotor | SDTMotor
| Opaque data structure representing a combustion engine object.

## Functions
SDTMotor * | SDTMotor_new (long maxDelay)
| Object constructor. More...
void | SDTMotor_free (SDTMotor *x)
| Object destructor. More...
void | SDTMotor_setFilters (SDTMotor *x, double damp, double dc)
| Update filter coefficients. Should be always called after setting the sampling rate with SDT_setSampleRate(). More...
void | SDTMotor_setRpm (SDTMotor *x, double f)
| Sets the Revolutions Per Minute (RPM) of the engine. More...
void | SDTMotor_setThrottle (SDTMotor *x, double f)
| Sets the throttle load. More...
void | SDTMotor_setFourStroke (SDTMotor *x)
| Simulates the operation cycle of a four-stroke engine.
void | SDTMotor_setTwoStroke (SDTMotor *x)
| Simulates the operation cycle of a two-stroke engine.
void | SDTMotor_setNCylinders (SDTMotor *x, int i)
| Sets the number of cylinders in the engine block. More...
void | SDTMotor_setCylinderSize (SDTMotor *x, double f)
| Sets the size of each single cylinder. The total volume of the engine is this value multiplied by the number of cylinders. More...
void | SDTMotor_setCompressionRatio (SDTMotor *x, double f)
| Sets the compression ratio of the engine. The compression ratio is computed dividing the cylinder volume at maximum expansion (piston down) by its volume at maximum compression (piston up). More...
void | SDTMotor_setSparkTime (SDTMotor *x, double f)
| Sets the width of the ignition pulse, compared to a full operation cycle. More...
void | SDTMotor_setAsymmetry (SDTMotor *x, double f)
| Sets the amount of irregularity in the operation cycle. More...
void | SDTMotor_setBackfire (SDTMotor *x, double f)
| Sets the amount of backfiring when the engine revs down. More...
void | SDTMotor_setIntakeSize (SDTMotor *x, double f)
| Sets the average length of the intake pipes. More...
void | SDTMotor_setExtractorSize (SDTMotor *x, double f)
| Sets the average length of the extractor pipes. More...
void | SDTMotor_setExhaustSize (SDTMotor *x, double f)
| Sets the length of the main exhaust pipe. More...
void | SDTMotor_setExpansion (SDTMotor *x, double f)
| Sets the amount of expansion of the main exhaust pipe. This is a feature commonly found in two-stroke engines, to avoid the passage of fresh fuel mixture into the exhaust system. More...
void | SDTMotor_setMufflerSize (SDTMotor *x, double f)
| Sets the average length of the muffler chambers. More...
void | SDTMotor_setMufflerFeedback (SDTMotor *x, double f)
| Sets the amount of energy dissipated by the muffler chambers. More...
void | SDTMotor_setOutletSize (SDTMotor *x, double f)
| Sets the length of the exhaust outlet. More...
void | SDTMotor_dsp (SDTMotor *x, double *outs)
| Signal processing routine. Call this function at sample rate to synthesize the engine sound. The output is written in an array of three doubles. The first value represents the sound picked up at the intakes, from the front of the vehicle; the second represents the engine vibrations, mostly heard inside the cabin; the third and last output represents the sound coming from the exhaust outlet, towards the rear of the vehicle.
