Design Proposal for 4-Cylinder Compression-Ignition Engine

Abstract

Nowadays, most of the vehicles runs on Diesel engines. We do not use coal-powered steam engines any more. Rudolf Diesel played a vital role in the modern era of transportation by inventing Diesel engines. The need for even bigger and more powerful engines brings the designers of such machineries to a challenging time but with the help of the fast growing Software industry, the challenges for better and fast design concepts can help the designers in any step of the technologically advanced production. The main goal of the thesis is to get knowledge on how a four cylinder four stroke compression-ignition Diesel engines operates and how each components that fall under it plays an important role in complete working of the engine by taking into the consideration of all the necessary design steps needed, starting with the dimensioning, strength checks of the crank mechanisms, finishing with a 3D CAD model and creating an animation of the engine. As per the objective, a workout is done with a concept design of the 4-cylinder 4-stroke compression ignition engine with the displacement of 1600-2000 cm3 and DOHC valve train with 4 valves per cylinder. The project leader provides basic information about the design process and the engine. CAD software is used for generating engine components and complete assembly. Last but not the least a stress analysis of the selected components of analysis of the performance of the engine system is carried out.
