A Car Engine Uses Two Major Mechanisms and Five Main Systems<\/h2>\n<p>The car engine is the power plant of the vehicle. It converts the chemical energy of fuel into thermal energy, then converts thermal energy into mechanical energy. A typical gasoline engine includes two major mechanisms and five main systems: crank linkage mechanism, gas distribution mechanism, cooling system, fuel supply system, lubrication system, ignition system, and starting system. Diesel engines generally have fewer gasoline-style ignition components because they use compression ignition.<\/p>\n<div class=\"ag-option-grid ag-card-grid-2-fixed\">\n<article class=\"ag-option-card\">\n<p class=\"ag-option-card__title\">Cooling system<\/p>\n<p>The cooling system usually includes a water tank, water pump, radiator, fan, thermostat, water temperature gauge, and drain switch. Automobile engines may use air cooling or water cooling, but most car engines are water-cooled. The system keeps the engine within the proper temperature range and helps prevent overheating or overcooling.<\/p>\n<\/article>\n<article class=\"ag-option-card\">\n<p class=\"ag-option-card__title\">Lubrication system<\/p>\n<p>The lubrication system includes the oil pump, collector filter, oil filter, oil passages, pressure limiting valve, oil gauge, pressure sensing plug, and dipstick. It reduces internal friction, helps extend engine life, and keeps engine parts cleaner.<\/p>\n<\/article>\n<article class=\"ag-option-card\">\n<p class=\"ag-option-card__title\">Fuel supply system<\/p>\n<p>Gasoline engine fuel systems may include a fuel tank, fuel gauge, fuel pipe, fuel filter, fuel pump, carburetor or injection system, and air filter. Diesel systems include injection pumps, injectors, governors, diesel tanks, delivery pumps, oil-water separators, diesel filters, injection advance components, and high- and low-pressure fuel lines.<\/p>\n<\/article>\n<article class=\"ag-option-card\">\n<p class=\"ag-option-card__title\">Ignition system<\/p>\n<p>The ignition system includes spark plugs, ignition coils, and distributors or related ignition control components. It provides ignition energy for combustion through high-voltage current and ignition timing control.<\/p>\n<\/article>\n<article class=\"ag-option-card\">\n<p class=\"ag-option-card__title\">Starting system<\/p>\n<p>The starting system includes the starter motor and related accessories. It starts a stationary engine and brings it into self-running operation.<\/p>\n<\/article>\n<\/div>\n<\/article>\n<\/section>\n<section aria-labelledby=\"engine-maintenance-essentials-title\" class=\"ag-block\" id=\"engine-maintenance-essentials\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">Maintenance Essentials<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Daily engine maintenance points<\/p>\n<h2 class=\"ag-heading\" id=\"engine-maintenance-essentials-title\">2. Engine Maintenance Should Match the Systems That Keep the Engine Running<\/h2>\n<p>From the engine structure above, several daily maintenance priorities become clear:<\/p>\n<ul class=\"ag-editorial-list\">\n<li><span class=\"ag-list-title\">Replace lubricating oil regularly<\/span>Fresh oil helps reduce friction and protect moving parts inside the engine.<\/li>\n<li><span class=\"ag-list-title\">Check the cooling system<\/span>Inspect the cooling system and replace coolant regularly to reduce overheating risk.<\/li>\n<li><span class=\"ag-list-title\">Clean carbon deposits<\/span>Throttle, intake manifold, combustion chamber, and injector carbon deposits should be cleaned when needed to maintain performance.<\/li>\n<li><span class=\"ag-list-title\">Replace air filters regularly<\/span>A clean air filter supports normal airflow and combustion efficiency.<\/li>\n<li><span class=\"ag-list-title\">Maintain the ignition system<\/span>Ignition system condition affects combustion stability and engine response.<\/li>\n<li><span class=\"ag-list-title\">Check the fuel system<\/span>Regular fuel system inspection helps maintain fuel delivery and engine reliability.<\/li>\n<\/ul>\n<\/article>\n<\/section>\n<section aria-labelledby=\"engine-technology-trends-title\" class=\"ag-block\" id=\"engine-technology-trends\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">Technology Trends<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">New car engine technologies and trends<\/p>\n<h2 class=\"ag-heading\" id=\"engine-technology-trends-title\">3. Traditional Engines Continue to Evolve Alongside Hybrid and Electric Powertrains<\/h2>\n<p>As the heart of the automobile, the engine depends on the coordinated work of all systems. Traditional engines continue to evolve as technology advances and environmental requirements increase.<\/p>\n<h3 class=\"ag-subheading\">Turbocharging vs. mechanical supercharging<\/h3>\n<p>Turbocharging and mechanical supercharging are two common forms of forced induction. Compared with mechanical supercharging, turbocharging does not directly consume engine crankshaft power in the same way, so it is widely used in many high-performance vehicles. Both technologies have advantages and disadvantages.<\/p>\n<ul class=\"ag-editorial-list\">\n<li><span class=\"ag-list-title\">Turbocharging<\/span>A turbocharger includes a turbine and a compressor. Exhaust gas drives the turbine, which then drives the compressor to compress air and send more air into the engine. This allows the engine to burn more fuel and increase power. Turbochargers are relatively simple and lower in cost, but pressure buildup can take time, so turbo lag may appear at low speeds.<\/li>\n<li><span class=\"ag-list-title\">Mechanical supercharging<\/span>Mechanical supercharging uses engine power to drive a compressor, compressing air and sending it into the engine. Mechanical superchargers are more complex and costly, but they respond quickly and can provide better immediate power response.<\/li>\n<\/ul>\n<h3 class=\"ag-subheading\">Hybridization and electrification trends<\/h3>\n<p>The original article cites China as an example: in 2023, sales of plug-in and range-extended hybrid passenger cars reached 2.754 million units, up 85.5% year-on-year. It also cites a forecast that by 2025, the share of China&#8217;s plug-in and range-extended hybrid passenger car sales would <a class=\"hyperlink\" href=\"http:\/\/www.pday.com.cn\/Htmls\/Report\/202401\/24542604.html\" target=\"_Blank\" rel=\"noopener\">rise to 40%<\/a>.<\/p>\n<div class=\"ag-option-grid ag-card-grid-2-fixed\">\n<article class=\"ag-option-card\">\n<p class=\"ag-option-card__title\">HEV hybrid vehicles<\/p>\n<p>HEVs use a combination of battery power and gasoline power. The battery, usually high-power lithium-ion, nickel-metal hydride, or sometimes a supercapacitor, mainly supports starting and acceleration. HEVs rely on regenerative braking instead of external charging. The original article notes that battery capacity is usually around 10 Ah.<\/p>\n<\/article>\n<article class=\"ag-option-card\">\n<p class=\"ag-option-card__title\">PHEV plug-in hybrid vehicles<\/p>\n<p>PHEVs have larger battery capacity, often ranging from 30 to 60 Ah in the original article. They can travel about 50 to 80 kilometers on battery power alone, then rely on gasoline for the remaining journey. Home charging under 10A takes longer, while high-current charging may reduce charging time to 10 to 30 minutes when specialized charging facilities are available.<\/p>\n<\/article>\n<\/div>\n<p>Hybrid drive systems may use parallel, series, or combined layouts. Their construction and working principles differ, and these differences can be explored in a dedicated hybrid powertrain article.<\/p>\n<h3 class=\"ag-subheading\">The future of conventional engines in the face of electrification<\/h3>\n<p>Automotive electric drive systems are reshaping transportation by using electric motors powered by rechargeable batteries. They reduce reliance on fossil fuels and help reduce tailpipe emissions. As the automotive industry continues to embrace electrification, electric powertrains, hybrid systems, and improved internal combustion engines will continue to influence vehicle design and maintenance.<br \/>\n<\/article>\n<\/section>\n<section aria-labelledby=\"engine-secrets-conclusion-title\" class=\"ag-block\" id=\"engine-secrets-conclusion\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">Conclusion<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<h2 class=\"ag-heading\" id=\"engine-secrets-conclusion-title\">4.
