The Denso 295050-1760 fuel injector has specific structural characteristics that define its design and functionality. Here’s a breakdown of its key features:

1. Injector Body & Housing

• Material: Typically made from stainless steel or high-grade plastic for durability and fuel resistance.

• Shape: Cylindrical body with a nozzle tip at one end and an electrical connector at the top.

• Mounting Style: Top-feed (fuel enters from the top, flows through the injector, and exits at the nozzle).

2. Nozzle Design

• Spray Pattern: Multi-hole nozzle (usually 4 holes or more) for fine atomization.

• Orientation: Cone-shaped spray for optimal fuel-air mixing.

• Sealing: Features an O-ring at the top and bottom to prevent fuel leaks.

3. Electrical Connector

• Type: EV1/USCAR-style connector (standard for many Japanese vehicles).

• Terminals: Two-pin connector (for high-impedance injectors, ~12 ohms).

• Wiring: Uses a pigtail harness for secure electrical connection.

4. Internal Components

• Solenoid Valve: Electromagnetically actuated to control fuel flow.

• Filter Basket: Small mesh screen at the inlet to prevent debris entry.

• Spring-Loaded Pintle: Ensures quick opening/closing for precise fuel delivery.

5. Flow & Pressure Specifications

• Flow Rate: ~ 550 cc/min (varies with pressure).

• Operating Pressure: Typically 2.5–3.5 bar (36–51 psi) for port injection.

• Impedance: High impedance (~12 ohms), making it compatible with most factory ECUs without a resistor box.

6. O-Rings & Seals

• Upper O-Ring: Seals the injector to the fuel rail.

• Lower O-Ring (or insulator): Seals the injector to the intake manifold.

• Material: Viton or similar fuel-resistant rubber.

7. Dimensions (Approximate)

• Length: ~ 60–70 mm (varies slightly by application).

• Diameter: ~ 14–16 mm (body width).

• Nozzle Tip Length/Shape: Short, tapered for proper seating in the intake manifold.

Key Features Summary

✔ High-impedance solenoid (no need for a resistor pack)
✔ Multi-hole nozzle for efficient fuel atomization
✔ Top-feed design (common in many Mitsubishi engines)
✔ EV1 connector (standardized electrical interface)
✔ Viton O-rings for long-term fuel resistance

Common Applications

• Used in Mitsubishi 4G63 (turbo & NA), 4G64, and 4G69 engines.

• Found in Evo, Lancer, Eclipse, Galant, and some Hyundai/Kia models with Mitsubishi-based engines.
