Vehicle Engineering: Analysis of Engine Types and Hill Climbing Design

This report delves into vehicle engineering, focusing on engine types, comparing internal and external combustion engines, and contrasting petrol and diesel engines. It highlights the advantages of lightweight vehicles, including ease of driving, higher power output, and lower maintenance costs. The report also examines the basic design principles of hill climbing vehicles, emphasizing the advanced transmission systems and constant mesh gearboxes that enable quick speed adjustments. Furthermore, it explains how road speed is generated through the transmission system, dependent on engine RPM, and provides a formula for calculating speed. The report concludes with a list of references from books, journals, and online resources related to sustainable electric vehicle technologies, hybrid vehicle emissions, electric vehicle traction machines, and the latest developments in hill climbing car design. Desklib provides students with access to this and similar solved assignments.

Vehicle Engineering

Types of Engines
1. Internal Combustion Engine – The combustion will be inside
the engine, and thus forces the piston to move up and down,
which helps in moving the vehicle.
2. External Combustion Engine – The combustion will be outside
the engine, and uses water or low boiling temperature liquid to
move the piston. In this way, by the help of steam the vehicle
will move forward.

Petrol Vs Diesel Engine

Advantages of using Light Weight Vehicle
 East to drive
 Power Output is more
 Engine speed is higher than heavy vehicle
 More environment friendly
 Maintenance cost is low

Basic Design of Hill Climbing Vehicle

Objective and findings
 The transmission system is very advanced,
which will help in driving the vehicle
 The speed is easily adjusted through the
actuation system
 Gear box is constant mesh, so the speed can
be adjusted very quickly at any position of
gear.

Constant Mesh Gear Box

Road Speed
 The speed generated through the
transmission system
 Dependent on the RPM of engine
 It can be calculated by
Mph = (RPM*Circumference)/(Gear
ratio*Final ratio*88)
