Small Gasoline Engine Industry: The Export Logic and Transformation Pressure Behind 10 Million Units of Output

I. What Exactly Is This Industry?

Small gasoline engines, commonly referred to as “general-purpose engines” or “small engines,” are reciprocating gasoline engines with a power rating generally below 25 horsepower (approx. 18.6 kW) and a displacement ranging roughly from 0.02L to 0.53L. They are divided into two-stroke and four-stroke variants. Their end applications are likely familiar: micro two-stroke engines found in lawnmowers and chainsaws, and four-stroke power cores used in portable generators and agricultural water pumps.

In one sentence: This is not a domestic demand-driven sector, but an export-oriented segment of Chinese manufacturing where exports serve as the absolute primary engine.

II. Hard Data: Output, Sales, Exports, and Market Size

1. Output & Exports: The 40-Million-Unit Scale

According to official statistics from the China Internal Combustion Engine Industry Association (CICEIA) Small Power Equipment Branch covering 74 full-member enterprises, the 2024 figures are as follows:

Total Output: Approx. 40.4501 million units (up 17.98% YoY)

Total Sales: Approx. 40.1573 million units (up 17.78% YoY)

Export Volume: Approx. 31.3184 million units (up 21.48% YoY)

Export Ratio: Approx. 77.99%, with domestic sales accounting for only about 22%.

This reveals a key fact: For every 4 small gasoline engines produced in China, about 3 are shipped overseas. North America, Europe, and Southeast Asia are the core destination markets.

2. Application-Oriented Perspective: From 8.96 Million to 9.30 Million Units

Shifting to an equipment matching perspective, CICEIA’s application data shows the following trends:

In 2021, total sales were 10.5276 million units, with agricultural machinery at 3.9044 million and garden machinery at 2.4988 million.

In 2022, total sales dropped to 7.4231 million units, with agricultural machinery at 2.9190 million and garden machinery at 1.6454 million.

In 2023, total sales were 6.6177 million units, with agricultural machinery at 2.4095 million and garden machinery at 1.4599 million.

In 2024, total sales rebounded to 8.9650 million units (up 35.47%), with agricultural machinery at 3.7294 million and garden machinery at 1.5016 million.

In 2025, total sales reached 9.2979 million units (up 3.71%), with agricultural machinery at 3.7606 million and garden machinery at 1.6289 million.

Agricultural machinery remains the largest single application scenario, accounting for over 40% of the total.

3. Market Size: ~$3.2 Billion Domestic, ~$80 Billion Global

Chinese Market: In 2025, the market size for small gasoline engines reached approximately RMB 22.845 billion (approx. $3.2 billion). Four-stroke models dominate the share.

Global Market: In revenue terms, the global general-purpose gasoline engine market was valued at approximately $7.9–8.2 billion in 2024. It is projected to reach $8.9–9.3 billion by 2030/2031, with a CAGR of about 1.9%–2.0%.

III. Competitive Landscape: Pricing Power Lies Abroad

The global top-tier is dominated by Honda, Briggs & Stratton, Kohler, and Yamaha. These players hold brand premiums and deep roots in European and American channels.

Chinese leaders include Zongshen Power, Loncin Motor, Huasheng Zhongtian, and Rato Technology. They rely on economies of scale and ODM/OEM delivery capabilities.

Hundreds of SMEs focus on low-price strategies, concentrated in low-end two-stroke and standard single-cylinder models.

A key observation is the extremely high export dependency. Leading enterprises generally derive 70%–85%+ of their revenue from overseas markets. This means the industry’s fate is tied to North American inventory cycles and EPA/CARB emission policies. Profit no longer lies in selling bare engines, but in “Engine + Terminal” integration, such as embedding engines into finished generators or pressure washers.

IV. Three Major Trends Rewriting the Rules

Emission Regulations:​ Non-road mobile machinery emission controls continue to tighten. High-emission two-stroke products are being phased out, while four-stroke models face cost pressures from electronic fuel injection and catalytic converters. This is structural reshuffling, not cyclical fluctuation.

Electrification:​ In handheld outdoor power equipment, lithium-ion battery substitution has advanced significantly in Western markets. However, for scenarios demanding high energy density like portable generators above 3kW, fuel engines remain irreplaceable for now. The most pragmatic strategy is a dual-track approach: defend the fuel engine base while actively entering the lithium/hybrid product line.

Emerging Markets:​ Demand in Europe and America is stabilizing, but demand continues to rise in Southeast Asia, Africa, and South America. Incremental opportunities for small-to-medium power engines lie more in these emerging regions than in saturated Western markets.

V. Practical Advice for SMEs

If you are a small or medium-sized manufacturer, consider the following:

First, stop exhausting yourself in naked price wars over bare engines. Without economies of scale, competing on cost leads to losses or penalties for cutting corners.

Second, dive deep into one terminal application scenario. Build a closed-loop product integrating engine, housing, control system, and after-sales service. This ensures longer viability than producing generic white-label engines.

Third, exporting is not a bonus; it is the entry ticket. You must tackle EPA/CARB certifications and overseas spare parts logistics, not just FOB pricing.

Fourth, leave an interface for the post-gasoline era. Gradually build technical reserves in EFI calibration and lithium-hybrid compatibility. Your admission ticket for the next industry reshuffle lies here.

VI. Summary

The small gasoline engine industry may not be glamorous, but it is profoundly real: an annual output of 40 million units, nearly 80% export dependency, and nearly half of global production capacity located in China. Over the next 3–5 years, the winners will not be the cheapest producers, but those who can balance emission compliance, channel branding, and product electrification.
