    ISSN: 2277-9655 [Allolkar* et al., 7(5): May, 2018] Impact Factor: 5.164 IC™ Value: 3.00 CODEN: IJESS7 IJESRT INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY SURVEY ON MULTI POINT FUEL INJECTION (MPFI) ENGINE Deepali Baban Allolkar*1, Arun Tigadi 2 & Vijay Rayar3 *1 Department of Electronics and Communication, KLE Dr. M S Sheshgiri College of Engineering and Technology, India. 2,3Assistant Professor, Department of Electronics and Communication, KLE Dr. M S Sheshgiri College of Engineering and Technology, India. DOI: 10.5281/zenodo.1241426 ABSTRACT The Multi Point Fuel Injection (MPFI) is a system or method of injecting fuel into internal combustion engine through multi ports situated on intake valve of each cylinder. It delivers an exact quantity of fuel in each cylinder at the right time. The amount of air intake is decided by the car driver by pressing the gas pedal, depending on the speed requirement. The air mass flow sensor near throttle valve and the oxygen sensor in the exhaust sends signal to Electronic control unit (ECU). ECU determines the air fuel ratio required, hence the pulse width. Depending on the signal from ECU the injectors inject fuel right into the intake valve. Thus the multi-point fuel injection technology uses individual fuel injector for each cylinder, there is no gas wastage over time. It reduces the fuel consumption and makes the vehicle more efficient and economical. KEYWORDS: Multi point fuel injection (MPFI), Cylinder, Gas pedal, Throttle valve, Electronic control Unit (ECU). I. INTRODUCTION Petrol engines used carburetor for supplying the air fuel mixture in correct ratio but fuel injection replaced carburetors from the 1980s onward.

  • Closed Loop Engine Management System
    Information Sheet #105 CLOSED-LOOP CONTROL SYSTEMS ON GASEOUS GENERATORS Frequently the engine used to drive the generator in a standby or prime power generator system is a 4-stroke spark ignition (SI) engine. While many smaller portable generators use SI engines fueled by gasoline, the majority of SI engine driven generators above 10kW are fitted with SI engines fueled by gaseous fuel, either natural gas (NG), or liquid petroleum gas (LPG). The majority of gaseous powered SI engines within a generator system are frequently referred to as having a Closed-Loop Engine Control System. In understanding Buckeye Power Sales necessary maintenance required to maintain optimum operation and performance of an SI engine using a closed-loop system, it is Reliable Power Professionals Since 1947 important to be aware of all the components within the system, their functions, and the advantages a closed-loop system. 1.0 WHAT IS A CLOSED-LOOP SYSTEM: The term “loop” in a control system refers to the path taken through various components to obtain a desired output. Used in conjunction with the word “closed” it refers to sensors measuring actual output along the path against required output. The various outputs measured along the path, or loop, are referred to as feedback signals. In a closed- loop system, the feedback along the path constantly enables the engine control system to adjust and ensure the right output is maintained as variations in ambient temperature, load, altitude, and humidity influence combustion and required output. So, in brief, closed-loop systems employ sensors in the loop to constantly provide feedback so the ECU can adjust inputs to obtain the required output.

Automotive electronics consists of advanced sensors, control units, and “mechatronic“actuator making it increasingly complex, networked vehicle systems. Electronic fuel injection (EFI) is the most common example of automotive electronics application in Powertrain. An EFI system is basically developed for the control of injection timing and fuel quantity for better fuel efficiency and power output. In this paper, we will explain various types of fuel injection system that are used most commonly nowadays and will also explain the various parameters considered during calculating,(using speed density method), base fuel quantity during runtime. We will explain the major difference between speed density method and alpha-n method and in the end, we will also show the MATLAB/Simulink model of fuel injection system for Single cylinder four stroke engine.

Typeset with LATEX 2ε Printed by LiU-Tryck, Linköping, Sweden 2014 i Abstract The torque response of the engine is important for the driving experience of a vehicle. In spark ignited engines, torque is proportional to the air flow into the cylinders. Controlling torque therefore implies controlling air flow. In modern turbocharged engines, the driver commands are interpreted by an electronic control unit that controls the engine through electromechanical and pneumatic actuators. Air flow to the intake manifold is controlled by an electronic throttle, and a wastegate controls the energy to the turbine, affecting boost pressure and air flow.

  • Transient Air Dynamics Modeling for an Advanced Alternative Fueled Engine
    Transient Air Dynamics Modeling for an Advanced Alternative Fueled Engine Undergraduate Honors Thesis Presented in Partial Fulfillment of the Requirements for Graduation with Distinction at The Ohio State University By Ryan V. Everett * * * * * The Ohio State University 2010 Defense Committee: Professor Giorgio Rizzoni, Advisor Dr. Shawn Midlam-Mohler Copyrighted by Ryan V. Everett 2010 ii ABSTRACT The EcoCAR challenge is a three year competition with a goal of re-engineering a 2009 General Motors crossover utility vehicle to improve vehicle emissions and fuel economy, while maintaining drivability and consumer acceptability. Ohio State’s team has selected a plug-in hybrid electric vehicle (PHEV) architecture with a 1.8 L CNG Honda engine as the auxiliary power unit. The Honda engine is converted to run on E85 fuel, which requires the engine control software to be rewritten. The purpose of this research is to write a feed forward air/fuel ratio (AFR) control algorithm to better manage fuel injection during transient engine events. AFR control has a major impact on engine fuel economy and tail pipe emissions. This research investigates the accuracy of using a dynamic intake manifold filling and emptying model coupled with a linear approximation of the Taylor Series expansion to predict air flow forward in time. To better estimate air flowing passed the throttle plate and into the intake manifold, a quasi-static effective area map of the throttle was created. The control algorithm uses the throttle effective area map to improve the accuracy of air flow estimation into the intake manifold because the MAF sensor is not a reliable flow meter during transient engine events.

  • Air Filter and Selected Vehicle Characteristics
    sustainability Article Air Filter and Selected Vehicle Characteristics František Synák *, Alica Kalašová and Ján Synák Department of Road and Urban Transport, University of Žilina, 01026 Žilina, Slovakia; [email protected] (A.K.); [email protected] (J.S.) * Correspondence: [email protected]; Tel.: +42-1907-230-469 Received: 12 September 2020; Accepted: 6 November 2020; Published: 10 November 2020 Abstract: While a vehicle is driving, the air filter is gradually being clogged. Thus, there is a condition for air mass delivered into the engine’s cylinders to be reduced. It can further degrade the vehicle’s ability to accelerate and, therefore, have an impact on road driving safety, or it can eventually make a vehicle performance worse or cause a change in the exhaust gas composition. The article pays attention to the impact of clogged air filter on selected vehicle characteristics including a vehicle’s dynamic features, fuel consumption and composition of the exhaust gases. The measurements have been performed under laboratory conditions. For higher result objectivity, the measurements have been done under some extreme conditions as well, with both the air filter fully clogged and forced air induction. The importance of the article lies in quantification of the impact of clogged air filter on selected vehicle features. The results from this article show a relatively low impact of air filter on the features studied. The biggest differences were measured under extreme conditions when the air filter had been almost fully clogged, or the air had been delivered into the engine under pressure. Keywords: air filter; air pollution; combustion engine; emissions; exhaust gases; fuel consumption; torque power 1.
