Understanding Engine Performance: A Comprehensive Guide
Understanding Engine Performance
Thermal Efficiency
Thermal efficiency is higher with increased combustion temperatures and reduced heat loss. It’s calculated as the ratio of effective power to fuel’s thermal power. Exhaust gases account for significant heat loss (35% in gasoline engines, 30% in diesel). Cooling systems also contribute to heat loss, removing about 30% of engine heat. Ultimately, combustion engines can only convert 35-50% of fuel energy into useful work.

Two-Stroke Engine Cycle
Work Cycle
The two-stroke engine completes its work cycle in two piston strokes, unlike the four-stroke engine which requires four strokes. The cycle consists of two main phases:
First Stroke: Exhaust, Scavenging, and Intake
- As the piston moves up from bottom dead center (BDC), exhaust gases exit through the exhaust port.
- Simultaneously, fresh air-fuel mixture from the crankcase enters the cylinder through the transfer port, pushing out the remaining exhaust gases. This process

Understanding the Internet of Things (IoT)
What is IoT and its Objectives?
The Internet of Things (IoT) refers to a network of physical objects, or “things,” embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet.
Key Objectives of IoT:
- Connectivity: Enabling everyday objects to connect to the internet.
- Data Collection: Gathering data from sensors and devices in real-time.
- Automation: Automating processes and tasks based on

Key Angles and Their Effects
Drift Angle
The drift angle is the angle between the actual direction a tire travels and the direction it is pointing. It arises from lateral forces acting on the vehicle and depends on tire flexibility and inflation pressure. Drift angle can cause variations in the vehicle’s trajectory and differences in the angles between the front and rear wheels.
Caster Angle
The caster angle is formed by the steering axis and the vertical
