Boat motors, regardless of the power and number of cycles, are thoroughly tested and tested before implementation. The materials and components used are of the highest quality, so all
modifications are characterized by increased reliability and correspond to the stated characteristics.

  • Two-stroke engines (DT) are presented in five versions with powers: 2.2; 9.9; 15; thirty; 40 horsepower. Suspended boat motors (PLM) of this type are convenient in terms of frequent
    shipments, since they have a lightweight design. They are quickly gaining momentum, easy to manage and maintain.
  • Four-stroke engines (DF) are represented by a wide power range (from 2.5 to 300 horsepower). Moreover, the gradation occurs with an optimal pitch, which allows you to accurately select the
    desired engine for the swimming facility.

All products can be divided into two groups according to engine power. The first (2-10 horsepower) are models for small boats, intended for amateur use. The second group, with an engine capacity
of 15-20 liters. forces already intended for pleasure craft of small capacity and yachts.

The second principle of division is associated with technical features and is based on the number of work cycles. Some engines operate on the principle of fuel intake — exhaust gases. Others
besides these also have intermediate cycles: compression and working stroke. Two-stroke engines are lighter, they are simpler in terms of design, maintenance and cheaper. Four stroke is an
example of excellence in technology. They are more economical, environmentally cleaner, have an increased efficiency, although they cost and are more expensive to maintain.

    3-2 IGNITION AND ELECTRICAL IGNITION SYSTEM PRINCIPLES OF OPERATION A digital CDI (condenser discharge ignition) system is employed on the DF9.9/DF15. The condenser built in the CDI unit stores the electrical energy generated by the condenser charge coil. The electrical energy stored in the condenser is released to the ignition coil primary windings by the ignition timing signal calculated by the CDI microcomputer from the pulser coil signals.

  • Page 50: Ignition Timing Control

    IGNITION AND ELECTRICAL 3-3 IGNITION TIMING CONTROL Outline The ignition timing varies based upon engine speed. The pulser coil monitor current engine speed and send signals to the CDI unit. Based on this signal, the CDI unit determines the optimum ignition timing and supplies voltage to the primary winding of the ignition coil.
