Core Product Advantages

This HT36‑ISG is an electronic‑fuel‑injection heavy‑oil UAV power plant, integrated starter‑generator drone engine and professional‑grade two‑stroke power system designed for long‑endurance industrial survey drones, fixed‑wing professional unmanned aircraft and hybrid‑power aerial equipment. Its main strengths are listed below:

EFI Heavy‑Oil Fuel‑Injection Structure
Adopts electronic fuel injection design and supports JP‑8 heavy‑oil fuel, featuring stable combustion, good high‑altitude adaptability and longer flight time for industrial UAV missions.
ISG All‑in‑One Electric Start and Power‑Generation Module
Built‑in starter‑generator assembly, 24V‑30A electric starting condition, stable DC24V‑255W power output at 6500 rpm to continuously supply power for airborne cameras, sensors and other loads.
Reliable‑Strong Power Output
36‑cc displacement delivers peak 4.5‑HP power at 9000 rpm, offering adequate thrust for medium‑long‑endurance fixed‑wing and multi‑rotor industrial‑use unmanned aerial vehicles.
Wide Stable‑Speed Operating Window
Stable working speed covers 3000‑8000 rpm, matching low‑speed cruise patrol, medium‑speed hovering and high‑speed fast‑flight working conditions of professional drones.
Multiple‑size Two‑Blade‑Propeller Compatibility
Compatible with 18×10, 19×8‑10, 20×8 two‑blade propellers, freely adjustable thrust and speed according to actual mission requirements.
Mature Ignition System and Standard Oil‑Fuel Mixing Specification
Independent ignition module works under DC 6V‑14.4V power supply; heavy‑oil and lubricant mixing ratio is 35:1, which effectively reduces internal mechanical wear during long‑time continuous operation.

Product Overview

1. Product Positioning for Industrial‑Grade Long‑Endurance Heavy‑Oil UAVs

HT36‑ISG is a two‑stroke EFI heavy‑oil piston‑type engine equipped with integrated starter‑generator. Compared with ordinary gasoline drone engines, it uses JP‑8 heavy‑oil fuel with higher flash‑point, better safety performance and outstanding high‑altitude adaptation, mostly applied in professional aerial survey, long‑time patrol and industrial‑grade unmanned aircraft projects.

The integrated ISG structure realizes convenient electric startup and onboard power‑supply function, suitable for aircraft with plenty of power‑consuming airborne equipment.

2. Operating‑Speed Property and Built‑In Power‑Generation Performance

The practical rotational‑speed scope ranges from 3000 rpm to 8000 rpm, and the engine reaches the maximum 4.5‑horsepower output at 9000 rpm.

When the motor runs at 6500 rpm, the ISG generator stably outputs 255‑watt 24‑volt direct‑current power. It adopts 24V‑30A starting parameters for rapid electric startup. Users can replace matched propellers to adjust flight thrust and cruising speed.

3. Ignition Configuration and Heavy‑Oil Lubrication Standard

The separate ignition unit weighs 130g and is powered by DC 6V‑14.4V 1000‑mAh power source to guarantee steady ignition spark under complicated outdoor environments.

JP8 heavy‑oil fuel needs to blend with full‑synthetic two‑stroke lubricating oil at 35:1 mixing‑ratio, which protects internal moving components and prolongs engine service life under long‑hour heavy‑duty operation.

Frequently Asked Questions (FAQ)

Q1: What kinds of drones is the HT36‑ISG heavy‑oil engine suitable for?

A1: This EFI heavy‑fuel power plant is well‑suited for industrial long‑endurance aerial‑survey fixed‑wing UAV, high‑altitude patrol aircraft and hybrid‑power unmanned aircraft. Its built‑in 24‑V generator can supply sustained power for cameras, laser sensors and other high‑power airborne equipment.

Q2: What benefits does JP‑8 heavy‑oil bring compared with regular‑gasoline drone engines?

A2: JP‑8 heavy‑oil features higher flash‑point, better‑safety property, stronger high‑altitude combustion adaptability and longer flight duration. The electronic fuel‑injection system can automatically adjust the fuel supply under varied altitude environments.

Q3: What fuel‑oil mixing ratio should I adopt?

A3: You are required to mix JP8 heavy‑oil and full‑synthetic two‑stroke‑special lubricating oil strictly at 35:1. Please refer to the official manual for fuel‑mixing, propeller‑matching and EFI parameter tuning guidance.
