{ "item_title" : "How Car Engines Work", "item_author" : [" Methez Visthrud "], "item_description" : "Most people drive for twenty years without ever knowing what happens under the hood. This book closes that gap.An engine is not hard to understand because it is mysterious. It is hard because almost nobody explains it in the order it actually works. How Car Engines Work starts with one sealed chamber and a moving wall, and builds outward - one mechanism at a time - until the whole machine makes sense.No prior knowledge is assumed. No tools are needed. Every term is introduced at the point where it first matters, and every chapter is built around a mechanism, because once the mechanism is clear the facts that follow stop needing to be memorised separately.What you will understand by the endHow the energy in fuel becomes rotation at the wheels, stage by stageWhy the four-stroke cycle needs four strokes, and what each one is forWhat pistons, connecting rods, crankshafts, camshafts and valves actually doWhere diesel and gasoline engines differ, and why each wins where it doesHow lubrication, cooling, ignition, intake and exhaust keep an engine aliveWhat the engine computer measures, and what a fault code does and does not tell youHow turbochargers and superchargers make an engine breathe harderWhat knocking, misfires and coloured exhaust smoke are telling youHow hybrid powertrains change the job the engine is doingA seven-step diagnostic method that replaces guessing with evidenceBuilt for understanding, not memorising52 technical illustrations, drawn in greyscale with numbered callouts. The visual language stays consistent from the first chapter to the last - the same pattern always means the same substance - so by the middle of the book you will read a diagram before you read its caption.36 Common Misunderstanding boxes correct the beliefs that actively block the next idea. An engine does not suck air in. Combustion is not an explosion. The cooling system is not there to keep the engine cold.36 Safety Warnings, placed where a real hazard exists in that chapter's subject rather than at fixed intervals, and written to be read before the work rather than after the injury.142 Knowledge Check questions with a complete answer key that shows the reasoning, not just the result.A 204-entry glossary, and an appendix of logs and inspection checklists to keep with the vehicle.What this book is notIt is not a repair manual, and it does not pretend to be. It deliberately gives no torque figures, service intervals or fluid capacities, because those belong to your specific engine, and taking them from a general book is how engines get damaged. What it gives you instead is the understanding to read your manufacturer's information and know what it means - and to walk into a workshop able to follow the conversation.Twenty chapters in six parts. Written for the curious owner, the student, and anyone who would rather understand why than memorise that.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/819/254/9798192547168_b.jpg", "price_data" : { "retail_price" : "24.99", "online_price" : "24.99", "our_price" : "24.99", "club_price" : "24.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
