Fuel Injection System for Small Motorcycles

Experimental analysis of a motorbike high speed racing engine

“…In such engines the throttling by the load control system at low regimes acts like a barrier to backflows, and it is not unusual that further throttling increases brake mean effective pressure. This is the main reason of the secondary throttle valve in almost all the stock engines, as confirmed by Wakimura and Nitta [31]. On the other hand, the secondary throttle has been locked wide open in these tests because of the high operation regimes of the engine.…”

Semi-Direct Injection Engine Modeling for Real Time Control

“…The PIM measurement was taken with a manifold absolute pressure sensor and sampled at 30 degrees After Bottom Death Center (ABDC). This position represents high linearity and accuracy [7]. The outcome shows that the predicted results are very good.…”
