Page 10: Fuels / Fuel System
Manual Smart M160 / 1– UL- Engine July 05 2.4. Fuels / Fuel System Use only unleaded, min. 95 octane fuel (unleaded Super = standard automotive fuel). Do not use any fuel additives! Remarks : Leaded fuels damage not only the catalytic converter but also the lambda sensor! The general rule also for engines not fitted with a catalytic converter is therefore: do not use leaded fuel! In case only Normal unleaded fuel is available, it can be used in exceptional... -
Page 11: Lubricants
Semi-synthetic or synthetic oils are recommended. The best oils currently on the market are classified “SJ” (API). The best oil you can use for this engine will meet the current Mercedes-Benz Specification 229.3 (includes 229.1). We cite an excerpt from MB Specification 229.3:... -
Page 12: Cooling System And Coolant
Use only antifreeze/anticorrosive fluids recommended by Mercedes-Benz. For further information, contact the nearest Mercedes-Benz or smart service station. In the event of coolant loss, determine cause, correct and refill as necessary. At the time of refilling, top up with the recommended ratio of water and anti- freeze/anticorrosive fluid. -
Page 13: Operating Limits
Manual Smart M160 / 1– UL- Engine July 05 Note: Ensure that the drive axes are perfectly parallel. Misalignments will provoke damage NEVER assemble the propeller axle without locating pins . Do not insert any spacers to extend the engine-propeller distance: this will increase the bending load on the gears beyond permissible limits ! Note that a new belt will initially lose some rubber;... - Page 14 Manual Smart M160 / 1– UL- Engine July 05 The diagram below indicates normal temperatures against RPM. The minimum permissible oil pressure is a function of the oil temperature and RPM. See diagram below (applies to engines when new) In the engines that have been in operation for longer periods, the indicated values can be lower by about 10%.

Page 15: Height
Manual Smart M160 / 1– UL- Engine July 05 Ecofly GmbH page 13 3.2. Height The turbocharger is configured such that the engine will deliver 60/74KW of power up to 2500m height. Reduce power setting above 2400m so that the turbocharger does not exceed its maximum rotational speed. -
Page 16: Ecu / Relay Box
Manual Smart M160 / 1– UL- Engine July 05 3.5. ECU / Relay Box Install the ECU so that the rear of the ECU is ventilated by cool ambient air. This arrangement is necessary to drain the heat from active components. Max. -
Page 17: Takeoff
Manual Smart M160 / 1– UL- Engine July 05 4.2. Takeoff Always set full power for takeoff. In addition to observing temperatures, monitor especially the indicated oil and manifold pressure. Leave engine at full power until you reach safe flying altitude; since the engine regulates itself, it is not necessary to power down! 4.3. -
Page 18: Checks After First 25Hrs (In Addition To 5.1.)
Manual Smart M160 / 1– UL- Engine July 05 5.2. Checks after first 25hrs (in addition to 5.1.) Check the entire power train for loose or missing nuts and screws. Replace or tighten as necessary. Check belt, belt tension, propeller drive and propeller bearings Check air filter Change oil, renew oil filter Clean and renew fuel filter if necessary... -
Page 19: Checks After 1500Hrs Or 15 Years
Manual Smart M160 / 1– UL- Engine July 05 Ecofly GmbH page 17 5.5. Checks after 1500hrs or 15 years We recommend full engine overhaul after 1500hrs. Contact your engine service station. Since these engines are produced in large numbers, it may be cheaper to buy a new engine (crankcase with power plant and cylinder head) and install it along with a new e-gas unit and turbocharger. -
