Trace TE750A

750 Horses. Unmatched Price to Performance Ratio

The TRACE TE750A is an experimental, next-generation V-8 piston engine designed to replace turbines in the 600 to 750 horsepower range. The additional 150 horsepower allows for faster take-off and climbing for short-field take-offs. The TE750A will complete FAA Certification in 2012, followed by an official debut in a Cessna Caravan.

The TE750A features a revolutionary camshaft design and electronic ignition system for greater fuel efficiencies and engine response than any engine in its class. The fuel and ignition systems can also be tuned for specific airframes to maximize performance and efficiency. Contact TRACE to begin engineering or retrofitting your airframe for TE750A compatibility.

World's Most Powerful Reciprocating Aviation Engine

TRACE engines outperform comparable turbines (450 to 750 horsepower range) in takeoff, climbing and at-altitude engine performance. The turbocharged TE750A V-8 engine produces 750 horsepower at takeoff and 500 horsepower continuously up to 20,000 feet (28,000 feet total service ceiling).

Comparable turbines suffer from a dissipated power band at higher altitudes due to the nature of their technology. For comparison purposes, it would require a 1000 horsepower turbine engine at sea level to match TE750A0’s performance at 20,000 ft.

Fuel Savings

The TRACE engine has a distinct fuel consumption advantage over turbines, especially for short flights and island hopping. Internal combustion engines such as TRACE are not subjected to inefficient turbine cycles. As a result, TRACE engines are 30 to 40% more fuel efficient than comparable turbines.

On a twin engine aircraft such as the King Air, turbines consume approximately 92 gallons per hour versus 52 gallons using TRACE engines. TRACE’s 40 gallon-an-hour savings, at $4.00 a gallon, equals $160 in savings every hour of operation.

Maintenance Savings

Turbine engine maintenance intervals are based on both hours and cycles - these can quickly add up over the life of an engine. TRACE engines are powered by internal combustion, meaning they will never require cycle-driven maintenance. TRACE’s lower maintenance requirements provide up to 50% annual cost-savings over the life of the engine.

For example, a typical turbine requires cycle service between 2000 and 6000 cycles or 2000 and 3000 hours, whichever comes first. TRACE engines do not require cycle maintenance and will ONLY undergo service after 1500 hours of flight time.

Engine Safety Testing

The TRACE V-8 engines have undergone extensive FAA testing to ensure reliability in the most demanding environments. In addition to proven V-8 technology, FADEC-equipped TRACE engines offer several advancements in electronic engine control that are designed to minimize pilot workload by automatically adjusting throttle and mixture.

Full Authority Digital Engine Control

The TRACE Electronic Ignition system is a Full Authority Digital Engine Control (FADEC) system designed for seamless engine response. The FADEC system features electronic fuel injectors in each intake passage that can be individually controlled by the FADEC computer to match all cylinders at every operating condition. FADEC is ideal for efficiently managing operating temperatures of both oil and coolant.

Unlike mechanical ignition systems, TRACE’s electronic system features solid state components to minimize moving parts and reduce maintenance requirements. FADEC also allows control of individual cylinders, spark advance and fuel flow for accurate response to over-temperature inputs from various sensors.Electronic ignition comes standard on the TE750A and can be fitted on OE600 models.

Additional Electric Ignition System benefits include:

  • Highly accurate control of spark and fuel for improved power, efficiency and longevity
  • Electronic fuel management for reduced pilot workload
  • Reliable starting regardless of hot or cold engine conditions or ambient temperatures
  • Low idle speed and excellent idle quality below 800 RPM
  • Possible use of unleaded fuel in conjunction with knock sensors
  • Solid state components for minimized maintenance

How It Works

The ignition system consists of two parts, ignition timing and fuel supply, which are digitally managed and monitored using a combination of redundant computer systems and power distribution models. All TRACE ignition components undergo a full load burn-in and rigorous process control testing to ensure 0% failure rates.

Redundancy ensures that if one system’s commands are lost, the other system will continue to operate uninterrupted. Input commands to the power module and FADEC computers are fed through dual redundant sensors that continuously measure engine parameters. These inputs are then converted to control commands that are delivered to the ignition system multiple times per second to ensure accurate engine response.

Vs. Mechanical Systems

Electrical ignition components consist of solid state components that significantly reduce failure rates when compared to mechanical systems. As there are no moving parts, TRACE electronic ignition systems are not subject to wear and tear and can operate indefinitely with proper use and maintenance. Idle speeds are also vastly improved with electronic ignition. The spark advance (idle control) in Magneto systems is fixed, meaning it must be set at or near its optimal power range for Take-Off conditions.

As a result, Magnetos are not optimized for lower engine speeds and put engines at risk of detonation and reduced efficiency. TRACE FADEC can adjust idle controls on-the-fly to ensure an optimal power band at all times.
