Design of Electronic Control Governor for a Single Cylinder Gasoline Engine Based on an Intelligent Sensing Algorithm

Abstract

At present, most large machinery and vehicle engines are electronically controlled but their electronic control systems are too expensive to be popularised and applied in small gasoline engines with relatively low prices. Therefore, small gasoline engines still use mechanical speed regulators. Mechanical speed regulators not only have the defects of inertia lag, friction resistance, inherent speed regulation and the like, but also have the disadvantage that dynamic performance and steady performance cannot be combined, which is not suitable for the increasingly improved speed regulation performance of gasoline engines. This paper describes the design of an electronically controlled intelligent governor for small gasoline engines. Starting from a low cost, it adopts the idea of "replacing part of the hardware with an intelligent sensing algorithm" and proposes an intelligent sensing algorithm scheme. It combines the "coarse tuning" of MAP and the "fine tuning" of adaptive expert PID. The system is proved experimentally and it not only overcomes the inherent defects of a mechanical governor and realises programmable speed regulation, but it also obtains good dynamic and steady performance, improves the power output of the engine, relieves the trouble of engine travelling and improves the freedom of carburetor matching.

Design of Automatic Packing System for Pipette Suction Heads

“…Fourth, the y-axis motor continues to work, the photoelectric switch reaches the first empty position, the y-axis motor stops working, the unlocking column crosses the sorting device, waiting for feeding, the sorting slot returns to the initial state, keeps the fixed suction head, and the impeller motor returns to work to feed the sorting slot (Pei et al, 2019). Fifth, after the sorting slot is filled with suction heads again, the impeller motor stops working; then the above steps are repeated, and the photoelectric switch successively reaches the second unlocking position, the second vacant position, the ninth unlocking position and the ninth vacant position; the second, third and ninth rows of suction head storage holes are filled one by one, and finally the filling of the suction head storage box is completed (Sun et al, 2020;Xu et al, 2018).…”

Suitability of Current Single-Cylinder Diesel Engines Available in Indonesia with New Indonesian National Standard (SNI 119:2020)

“…The study results showed that optimal fuel pressure can be obtained even at low engine speeds. Sun et al (2020) also improved the performance of diesel motors through fuel injection by applying electronic governor control with an intelligent sensing algorithm, resulting in increased power, reduced fuel consumption, and enhanced operational stability. Kapilan et al (2009) reported the same trend of increasing fuel injection pressure to improve engine performance.…”
