Power exhibitions bring together renowned engine brands such as Cummins, , MTU, Shangchai, Yuchai, Perkins, Deutz, Scania, Briggs & Stratton, Fiat, and more. The introduction to engines is as follows: Engine: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. Brief Description: The engine block forms the skeleton of the engine and serves as the installation base for all its mechanisms and systems. It houses all major components and accessories of the engine, both internally and externally, and withstands various loads. Therefore, the engine block must have sufficient strength and rigidity. The engine block assembly mainly consists of components such as the cylinder block, cylinder liner, cylinder head, and cylinder gasket.

When I was researching, I noticed that most mainstream global automakers develop their own engines, but there actually aren't many independent manufacturers specializing solely in engines. Common examples like Ford's Ecoboost and Toyota's Dynamic Force series are in-house technologies from major manufacturers. However, some niche performance cars commission specialized engine manufacturers for custom builds. For instance, Koenigsegg's twin-turbo V8 is made by British company Cosworth, which also supplies engines for Formula 1 racing. In the commercial vehicle sector, there's greater reliance on independent brands - Cummins diesel engines are particularly common in trucks. Some brands like have unique technologies; their Skyactiv-X compression-ignition gasoline engine is considered cutting-edge. Recently, Chinese brands have made significant progress - Changan's Blue Whale engines are approaching Toyota's thermal efficiency, and Chery's Kunpeng hybrid system boasts impressive specifications.

Those who are into car modifications are surely familiar with those legendary engine brands. Mitsubishi's 4G63 Red Top became iconic in the EVO, easily pushing 500 horsepower with just a tune. Nissan's RB26, despite being discontinued for two decades, remains a staple in drag racing. For American muscle, GM's LS-series small-block V8 stands out—huge tuning potential at an affordable price. Over in Germany, BMW's B58 inline-six turbo has been gaining popularity lately, delivering 380 horsepower straight from the factory. The engines used in Italian Maseratis produce an undeniably mesmerizing exhaust note. And if extreme lightweighting is the goal, check out British GKN's electric motor systems—they're a third lighter than traditional engines when used in hybrid hypercars.

Common household cars are mainly categorized into several types: Japanese brands like , Honda, and Nissan each have their Earth Dreams and HR series. The German Volkswagen's third-generation EA888 engine has significantly reduced oil consumption, while BMW's B-series modular engines enjoy a good reputation. American GM's Ecotec small-displacement turbo engines are fuel-efficient but noticeably shaky. Hyundai and Kia's Smartstream new technology improves fuel efficiency by 5%. French brands PSA and Renault share the 1.2T three-cylinder engine. Chinese brands like Geely and Volvo share the Drive-E series, and Changan's Blue Whale engine boasts an impressive 40% thermal efficiency. Emerging brands such as BYD's Xiaoyun hybrid-dedicated engine lead globally with a 43% thermal efficiency.

Truck drivers should be most familiar with these diesel engine brands. The American Cummins ISX series is commonly found in heavy-duty trucks, while the Isuzu 4JJ1 is known for its durability and is well-suited for vehicles. Deutz's V8 diesel engines are widely used in special-purpose vehicles. In China, Weichai's WP13 holds the top market share, and Yuchai engines have a good reputation for fuel efficiency. Among natural gas engines, the X15N from Westport is gaining popularity recently. In marine engines, Mitsubishi Heavy Industries' UE series is legendary. In the generator sector, Perkins' small-power units are exceptionally quiet, while Yunnan Diesel Engine's YN series offers high cost-effectiveness in the domestic market. Single-cylinder diesel engines from Changchai are often seen in agricultural machinery, praised for their simple structure and easy maintenance.

In addition to OEM engines, there are several professional aftermarket brands worth noting in the modification sector. Edelbrock from the USA offers cylinder heads that can boost horsepower by 20%, while Japan's HKS provides turbo kits that breathe new life into rotary engines. UK-based Cosworth not only produces racing engines but also offers ultra-precision Duratec aftermarket parts for civilian use. Domestically, emerging brands like Racetech focus on lightweight piston and connecting rod solutions. It's particularly noteworthy that some engines, though branded under one name, may originate from different sources. For instance, AMG engines were previously outsourced to Brabus but are now produced in-house by . Tesla models utilize motors supplied by Taiwan's Fukuta Motor, highlighting how these behind-the-scenes brands critically influence overall vehicle performance.
