Gas Engine

Gas Engine is an item in Scrap Mechanic.

Overview[ | ]

An engine with fixed speed and adjustable power, ideally suited to powering vehicles. Can be connected to a driver's seat or triggers.

Usage[ | ]

After you place the engine, you must turn it on in order for it to work. Keep in mind, if you plan on having the engine controlled by a Driver's Seat or a trigger, you should connect it before starting the engine. If you connect an engine to bearings without connecting the engine to a control part, the engine is active, and if it isn't on the Lift, the engine will automatically start. Removing a connected control part will automatically start the engine as well.

Press E on the engine to bring up the GUI. Click and drag the slider to any position above OFF to activate it. The slider controls the power of the engine, not the speed (speed is constant). The heavier the vehicle is, the more power is needed to move it. If it is set too low for the vehicle's weight, the vehicle will move slowly or not move at all. If it is set too high for its weight, the vehicle may flip over frequently. Because of this, the power setting should be proportional to the weight of the vehicle.

In Survival Mode, the Gas Engine requires Gasoline in order to function. This requires the Gasoline to either be placed directly into the engine or indirectly via a connected Gas Container, which will be slowly consumed as the engine is used. The Gas Engine can be upgraded with Component Kits to increase the amount of possible connections, increase its maximum available power, and improve its fuel efficiency.

Upgrades[ | ]

Upgrading the Gas Engine adds +2 Bearing connections, +2 "gears" (power slider settings), and +2 fuel efficiency per level.

A level 1 Gas Engine starts out with a maximum of two Bearing connections, restricting vehicles to two-wheel drive. Level 2 provides two more connections, allowing for a four-wheel drive vehicle.

Tips[ | ]

  • Attaching one or more Gas Engines (or Electric Engine) to multiple Bearings along a single 'shaft' will produce more power at the expense of more fuel. This is great for bulky heavy vehicles. However the more bearings used along a 'shaft', the more unstable the 'shaft' becomes.
