“…The graphics of the Figs. 19 and 20 shows the trend of CO and CO 2 emissions respectively. The value of CO for the throttle opening of 90% is relatively low, and the CO 2 to the same conditions also, this is because small amount of fuel, in proportion to the quantity of the intake air, is injected, so the air-fuel mixture is too poor.…”

“…The assembly of the injector on the cylinder head, mainly its inclination, is tted considering the reduction of the fuel short-circuit, a good air-fuel homogenization and a minimal fuel impingement on the piston top. Very interesting studies about the importance of the position of the injector can be seen in [18]; [19]; [20].…”

This study presents the design and construction of an electronic low-pressure gasoline direct injection system for two-stroke engines, with the objective to study engine performance and the emission of exhaust polluting gases, maintaining the expectations of this type of engine. The investigation includes a test bench with an incorporated engine and the required control devices for this, as well as a gas analyzer Class 0, a Computerized Data Acquisition and several tools for displaying and process all the electronic signals from the engine in real time. In order to manage this system, a custom electronic injection control unit has been designed and built, which allows control the fuel injection timing and duration. This unit uses the signal from an inductive sensor installed in the crankshaft as a reference and synchronization point. Additionally, modifications have been made to the fuel feeder circuit and the electronic of the test engine, as well as to some parts of the mechanism in order to adapt them to this technology. The implementation of the engine tests is described, and the performance and operational points of the original system and those of the new injection system are evaluated.
