throttleless

Adjective

throttleless (not comparable)

1. Not involving a throttle; unthrottled.
   • The next logical step in valve timing flexibility and control are fully variable mechanical systems like the BMW Valvetronic system [7], which gives increased flexibility over valve timing, duration and allows, for the first time, the ability to achieve throttleless load control with a mechanical...2002, Jeff Allen, Don Law, “Production Electro-Hydraulic Variable Valve-Train for a New Generation of I.C.

   • Engine performance has been mapped at shaft speeds from 2000 to 12,000 RPM, at altitudes from sea level up to 20,000 ft. and for a range of inlet pressures representative of throttling and supercharging. Mixture strengths were varied to evaluate the potential range of throttleless operation for...2002, Alvin Lowi Jr., “Designing a Miniature Engine for Large-Engine Performance”, in SAE Transactions, volume 112, number Section 3: JOURNAL OF ENGINES, page 1819
