The show also tested a carburetor that, according to its manufacturer, could improve fuel efficiency to 300 miles per US gallon (0.78 L/100 km). However, the device actually made the car less fuel efficient. They also determined that a diesel-powered car can run on used cooking oil though they did not check whether it damaged the engine.
Another reason to change the electronic control unit map is if there are engine, intake, or exhaust modifications to the car. These "bolt-on" modifications alter the way that the engine flows, often causing the air to fuel ratio to change. Without re-mapping the fuel tables, some of the performance gains from the modifications may not be realized.
It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. [1] GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.
Variable valve lift (VVL) is an automotive piston engine technology which varies the height a valve opens in order to improve performance, fuel economy or emissions. There are two main types of VVL: discrete, which employs fixed valve lift amounts, and continuous, which is able to vary the amount of lift.
The pulse-and-glide strategy is proven to be an efficient control design in both car-following [26] and free-driving scenarios, [28] with up to 20% fuel saving. In the PnG strategy, the control of the engine and the transmission determines the fuel-saving performance, and it is obtained by solving an optimal control problem (OCP).
A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.
To make things extra hands-off, you can control all the action via app. Thanks to the M210's built-in infrared sensor, this little robo-pal can automatically detect walls, stairs and more, without ...
Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be mutually exclusive; an engine may be de-tuned with respect to output power in exchange for better economy or longer engine ...
