Honda BF40 LRTU - Boat Motor 40 HP: Complete Overview of Technical Specifications and Features
Introduction to Honda BF40 LRTU
Honda BF40 LRTU is a 4-stroke outboard motor with 40 HP, representing the perfect combination of Japanese precision, innovative technologies, and reliability. This long-shaft motor (Long shaft) is ideal for medium-sized boats, RIB boats, aluminum boats, and sports vessels with a length of 4-6 meters.
Advanced Technologies and Features
1. PGM-FI Electronic Fuel Injection
Programmed fuel injection (PGM-FI) ensures precise dosing of the air-fuel mixture into each cylinder. thus it is:
- Extremely starting under all conditions
- Immediate throttle response
- Excellent fuel consumption
- Reduced harmful emissions
2. BLAST™ System (Boosted Low Speed Torque)
BLAST system significantly improved at low speeds
- Activates at full throttle below 3,500 rpm
- Provides smooth transition from low to high speeds
- Improves "hole shot" performance
- Optimizes torque at start
3. ECOmo Technology (Economically Controlled Motor)
Lean burn control system:
- Reduces fuel consumption by up to 20% compared to competition
- Minimizes NOx, HC, and CO emissions
- Allows economical operation at cruising speed
- Maintains performance with reduced emissions
4. Lean Burn Control
Advanced combustion control:
- Allows burning of a leaner fuel mixture
- Significantly reduces fuel consumption at cruising speed
- Optimizes performance in various operating modes
