What are the differences between transverse and longitudinal engines?

[OElliana]

Differences between transverse and longitudinal engines: 1. Placement method differs: Transverse engines adopt a horizontal placement; longitudinal engines adopt a vertical placement. 2. Drive method differs: Transverse engines typically use front-wheel drive; longitudinal engines usually employ rear-wheel drive or four-wheel drive. An engine is a machine capable of converting other forms of energy into mechanical energy, applicable both as a power generation device and referring to the entire machine including the power unit, such as gasoline engines and aircraft engines. Types include internal combustion engines, external combustion engines, electric motors, etc. The engine block forms the skeleton of the engine, serving as the installation base for all its mechanisms and systems, housing all major components and accessories internally and externally, and bearing various loads.

The differences between transverse and longitudinal engines are quite significant. Let's start with the layout: A transverse engine is parallel to the front wheels, fitted at the front of the engine bay, with the drivetrain directly connected to the front axle. This is commonly seen in front-wheel-drive vehicles like the Toyota Camry. The benefits include high space utilization, a spacious interior, and comfortable front seats. On the other hand, a longitudinal engine is aligned with the length of the car, such as in the Mercedes-Benz C-Class, making it easier to connect to rear-wheel or all-wheel-drive systems, with a lower center of gravity for better stability at high speeds. In terms of drivetrain, transverse engines are mostly front-wheel drive, offering slightly lower transmission efficiency but greater agility for city driving. Longitudinal engines support rear-wheel drive, providing better acceleration but potentially higher fuel consumption. The impact on space is noticeable: transverse-engine cars have shorter engine bays, smaller trunks but more cabin space, while longitudinal-engine cars have longer engine bays, which may affect passenger space but improve overall balance. In practical driving, transverse-engine cars have smaller turning radii, making parking easier, whereas longitudinal-engine cars offer more precise handling. Maintenance-wise, transverse engines are easier to service, such as replacing spark plugs, while longitudinal engines may require specialized tools. In summary, the choice depends on needs: transverse engines are better for daily commuting, while longitudinal engines excel for performance-oriented driving.
