Lean-burn refers to the burning of fuel with an excess of air in an internal combustion engine. In lean-burn engines the air–fuel ratio may be as lean as 65:1 (by mass). The air:fuel ratio needed to stoichiometrically combust gasoline, by contrast, is 14.64:1. The excess of air in a lean-burn engine emits far less hydrocarbons. High air–fuel ratios can also be used to reduce losses caused by other engine power management systems such as throttling losses.

thumb|A CNC-milled, single piece axial compressor blisk A blisk (portmanteau of bladed disk), also known as an integrally bladed rotor (IBR), is a turbomachinery component consisting of a rotor disk and blades made as a single part instead of a disk assembled with individual removable blades. Blisks generally have superior aerodynamics than conventional rotors with single blades and are lighter. They may be made by additive manufacturing, casting, machining from a solid piece of material, or welding blades to a rotor disk. The term blisk is used mainly in aerospace engine design.

Jetronic is a trade name of a manifold injection technology for automotive petrol engines, developed and marketed by Robert Bosch GmbH from the 1960s onwards. Bosch licensed the concept to many automobile manufacturers. There are numerous variations of the technology offering technological development and refinement, all but the Mono-Jetronic produced 1988-1995) being multi-point injection systems.

BlueTEC is Mercedes-Benz Group's marketing name for engines equipped with advanced NOx reducing technology for vehicle emissions control in diesel-powered vehicles. The technology in BlueTec vehicles includes a selective catalytic reduction (SCR) system that uses diesel exhaust fluid, and a system of NOx adsorbers the automaker calls DeNOx, which uses an oxidizing catalytic converter and diesel particulate filter combined with other NOx reducing systems.
