Mechanical Systems for Beginners

How to Repair Small Engines teaches how small engines work, why they fail, and how to diagnose problems using clear, practical mechanical reasoning. It covers fuel, air, ignition, and compression systems, along with routine maintenance and common failure patterns. The emphasis is on understanding root causes and applying safe, repeatable troubleshooting methods to everyday equipment such as lawnmowers, generators, and snowblowers.

How a Gas Engine Works explains the operation of gasoline engines by breaking down the four-stroke cycle, airflow, fuel delivery, ignition timing, and power production. It walks through how individual components and systems work together during each phase of engine operation. The book builds a solid mechanical understanding of engine behavior, providing readers with a clear framework for recognizing how gasoline engines produce power and respond under load.

How a Diesel Engine Works explains the operation of diesel engines by examining compression ignition, air and fuel flow, timing, and power production. It details how diesel engine systems work together through each stage of operation under varying loads and conditions. The book builds a clear mechanical framework for understanding diesel engine behavior, efficiency characteristics, and response to real-world operating demands.

How a Small Engine Works explains the operation of small gasoline engines by examining intake, compression, ignition, exhaust, and power transfer. It details how core engine components and support systems work together through each stage of operation under varying loads and operating conditions. The book builds a clear mechanical framework for understanding small engine behavior, efficiency, and performance in real-world equipment use.

How a 2-Stroke Engine Works explains the operation of two-stroke engines by examining intake, compression, ignition, scavenging, and power delivery within a single crankshaft cycle. It details how fuel, air, lubrication, and exhaust flow interact through each phase of operation under changing loads and speeds. The book builds a clear mechanical framework for understanding two-stroke performance, efficiency, and failure behavior in real-world power equipment.
