Most motorcycles in developing countries use carburetor systems as the fuel delivery method especially for models with the cubic capacity of less than 125cc. However, small gasoline fuelled engines operating using carburetor system suffer from low operating efficiency, waste of fuel and produce higher level of hazardous emissions to the environment. In this study, an electronic control unit (ECU) is designed and simulated for a retrofit fuel injection (FIS) system. The ECU is targeted to have a simple design, reliable and offers all of the necessary functions of the modern ECU. The simulation results shows that the designed ECU can determine the injection period as close to the proposed value and can drive the injector efficiently based on the generated PWM pulse.

In the current scenario of automotive industries, it is much challenging for the research and developers to develop updated engines/vehicles to satisfy the proposed demands of environmental policy levels. To achieve the expected demands of emissions coming out from an engine exhaust not only with the help of converters in the exhaust pipe line but also the emissions should be controlled during burning of fuel with air in the ignition chamber itself. The controlled combustion of fuel and air requires not only the control fuel injection timing with duration of injection and tune up of the complete fuel injection system with hardware components of ECU but also requires the control of ignition timing. The complete electronic control for petrol engine with direct injection unit is required to communicate between PC and an engine. CAN with SPI interface is used to communicate the electronic control unit with engine

The advancement in embedded systems, which includes the mass deployment of internet-connected electronics, allows the concept of Internet of Things (IoT), to become a reality. This paper discusses one example of how an internet-connected embedded system is utilized in an automotive system. An Electronic Control Unit (ECU), which functions as a control unit in a fuel injection system, are equipped with Wi-Fi capability and installed on 110cc motorcycle. The ECU is connected to multiple sensors that is used by the ECU as part of control system, as well as giving raw data in real time to the server by using Wi-Fi as the communication medium. The server will accumulate data transmitted from ECU by using MQTT protocol, chosen due to its minimal data profile. The data can be visualized through web portal, or opened by any other web-enabled devices. The data collected may also be used later for any other purposes, such as On-Board Diagnostics (OBD) system, etc.

This paper describes an optimal design procedure for improving the injection rate histories of an electronic control diesel fuel injection system (ECD-FIS) with sleeve-timing-controlled pump. The research objective was to develop an approach for upgrading an existing ECD-FIS by performing only some low-cost modifications on its design. Therefore, the design variables are related to a relative small number of geometrical and control parameters of the injection system. The geometrical parameters influence only the shape of a rational Be´zier curve, representing the cam profile of the pump. The control parameters influence the injection timing and injection quantity. These control parameters are introduced into the set of design variables in order to enable good results over the whole engine operating regime. The design problem is formulated in a form of a non-linear problem of mathematical programming. Several operating regimes are simultaneously taken into account by an appropriate objective function while some geometrical properties of the cam profile as well as some injection parameters are kept within acceptable limits by the imposed constraints. The theory is illustrated with a numerical example.

The article presents results of investigation on the combustion of a mixture of oil from pyrolysis of tires and basic fuel in an internal combustion reciprocating piston engine. The tested fuel consisted of: diesel oil and oil from pyrolysis of tires at amount of 10% by volume. The tests were carried out on a single-cylinder naturally aspirated compression-ignition engine. The engine is equipped with a common rail fuel injection system and an electronic control unit that allows changing injection timing. A comparative analysis of pressure-volume charts for the reference fuel, which was diesel, and for a mixture of diesel with the addition of 10% oil from tire pyrolysis was carried out during the study. Injector characteristics for the reference fuel and the mixture were determined. Engine efficiency for both fuels was determined. Unrepeatability of the engine work cycles for the diesel fuel and the tested mixture was calculated. Finally, the share of toxic exhaust components in exhaust gases was analyzed. It was found that pyrolisys oil from tires can be used as additive to regular diesel fuel at amount up to 10%, however, toxic exhaust gases emission was increased.
