  • torque
  • The design is novel with a dovetail attachment of the disc packs, allowing lower stress and allowing the use of next generation materials such as ceramics, composites and nanocomposites to improve the maximum temperature and the maximum RPM of the engine, thereby producing more horsepower and torque. (patentgenius.com)
  • The M-series engine produced 115 hp (86 kW) and 212 lb⋅ft (287 N⋅m). of torque. (wikipedia.org)
  • The valves actuate at particular engine frequencies (i.e. rpms) to produce optimal torque/horsepower output at any given engine speed. (wikipedia.org)
  • They are not as common as turbochargers because they use the torque produced from the engine to operate. (wikipedia.org)
  • rotation
  • The engine can kick back, causing sudden reverse rotation. (wikipedia.org)
  • Many manual starters included a one-directional slip or release provision so that once engine rotation began, the starter would disengage from the engine. (wikipedia.org)
  • In the event of a kickback, the reverse rotation of the engine could suddenly engage the starter, causing the crank to unexpectedly and violently jerk, possibly injuring the operator. (wikipedia.org)
  • Superchargers use various different types of compressors but are all powered directly by the rotation of the engine, usually through a belt drive. (wikipedia.org)
  • crank
  • The hand-crank method was commonly used to start engines, but it was inconvenient, difficult, and dangerous. (wikipedia.org)
  • with an advanced spark setting, the engine could kick back (run in reverse), pulling the crank with it, because the overrun safety mechanism works in one direction only. (wikipedia.org)
  • One aspect of the invention lay in the realization that a relatively small motor, driven with higher voltage and current than would be feasible for continuous operation, could deliver enough power to crank the engine for starting. (wikipedia.org)
  • mach
  • For example, the Lockheed SR-71 Blackbird jet could fly continuously at Mach 3.1 while some parts were above 315 °C (600 °F). Another area of concern for sustained high-speed flight is engine operation. (wikipedia.org)
  • The specific impulse (Isp) of air-breathing engines are superior to rockets over a wide range of Mach numbers. (wikipedia.org)
  • Current research and development is focused on engine operation at Mach 5 cruise at an altitude of 30 km. (wikipedia.org)
  • Therefore, for the DASS Engine to operate beyond the target 30 km and Mach 5 operating conditions, the design will be modified. (wikipedia.org)
  • Characteristics
  • The aim was to provide customers with substantial benefits in terms of fuel economy and fun-to-drive while maintaining the engine intrinsic comfort characteristics, based on a smooth combustion process and on light structures and components. (indianautosblog.com)
  • Atkinson
  • Adapted specifically for the hybrid powertrain and a first for premium performance sedans, the 3.5-liter V6, DOHC engine benefits from several technical improvements including the adoption of the Atkinson Cycle engine design to optimize the fuel-efficient benefits of Lexus Hybrid Drive. (dieselstation.com)
  • The engine runs on the Miller cycle, a variant of the Atkinson cycle used on hybrid vehicles . (autoblog.com)
  • high
  • Hypertech's engineers have cracked the code to bring their award winning, high performance engine tuning to late model cars and trucks. (tirerack.com)
  • Cooling is also needed because high temperatures damage engine materials and lubricants. (wikipedia.org)
  • High performance engines frequently have additional oil, beyond the amount needed for lubrication, sprayed upwards onto the bottom of the piston just for extra cooling. (wikipedia.org)
  • Extending its operating range including high load boundary towards full load and low load boundary towards idle in order to allow the CAI engine to meet the demand of whole vehicle driving cycles, has become one of the key issues facing the industrialisation of CAI/HCCI technology. (sae.org)
  • In addition, during transients including tip-outs, high levels of dilution can occur for multiple combustion events before either the external exhaust gas can be adjusted and cleared from the intake or cam phasing can be adjusted for correct internal dilution. (sae.org)
  • For cord-wound starters, a kickback could pull the operator towards the engine or machine, or swing the starter cord and handle at high speed around the starter pulley. (wikipedia.org)
  • The J52 engine was located in a pod located beneath the rear fuselage, giving it an appearance similar to the Lockheed X-7 high-speed experimental drone. (wikipedia.org)
  • High compression on a naturally aspirated engine can reach the detonation threshold fairly easily. (wikipedia.org)
  • Engines fitted with a decompressor can also be stopped by operating the decompressor, and in a vehicle with a manual transmission it is sometimes possible to stop the engine by engaging a high gear (i.e. 4th, 5th, 6th etc.), with foot brake and parking brake fully applied, and letting out the clutch quickly to slow the engine RPM to a stop, without moving the vehicle. (wikipedia.org)
  • The turbine exit gases still contain considerable energy that is converted in the propelling nozzle to a high speed jet. (wikipedia.org)
  • High heat release and pressure rise rates contribute to engine wear. (wikipedia.org)
  • performance
  • Traditional methods of improving performance such as increasing capacity and air intake through forced induction also results in more fuel being consumed. (edu.au)
  • If this layer enters the air intake of a jet engine, it can affect performance. (wikipedia.org)
  • That means it delivers the energy-saving benefits of a series hybrid combined with the performance benefits of a parallel hybrid. (automobilesreview.com)
  • All Hypertech products are perfect for vehicles already modified with performance intake and/or exhaust products and are street-legal for use in all 50 states (C.A.R.B. E.O. or pending). (tirerack.com)
  • In this paper, a novel cost-effective air hybrid powertrain concept for buses and commercial vehicles, Brunel Regenerative Engine Braking Device (RegenEBD) technology, is presented and its performance during the braking process is analysed using the Ricardo WAVE engine simulation programme. (sae.org)
  • In this work, systematic investigation has been carried out on the performance of the hybrid engine concept through detailed gas dynamic modelling using Ricardo WAVE software. (sae.org)
  • At the other end of the scale, performance tuning of an engine can involve revisiting some of the design decisions taken at quite an early stage in the development of the engine. (wikipedia.org)
  • When used on inline engines, parallel twin turbos are commonly applied with two smaller turbos, which can provide similar performance with less turbo lag than a single larger turbo. (wikipedia.org)
  • The acoustic liners' performance can be verified in dedicated experimental test rigs, by means of virtual prototypes or by means of ground tests on full-scale engines. (wikipedia.org)
  • petrol engine
  • Thus in the rare case of throttle linkage rupture, it is very easy to bring a runaway petrol engine to a stop by switching off the ignition. (wikipedia.org)
  • cylinders
  • the engine block is made short and compact by setting the cylinders into two banks of three or four cylinders each (Figures 1.9 and 6.2). (coursehero.com)
