Alternative Fuel Solution: Utilizing an Older Chevy Truck Fueled by Wood for Economical Driving

If you aren’t driving an EV, then you’re just like many of us seeking a break at the fuel pump. Even though gasoline prices in my area are lower than the national average, they still remain significantly higher than what they used to be, and I’m exhausted by it. If only I could get my hands on an old squarebody Chevrolet pickup equipped with a small-block V8 that runs on firewood.

That seems like it might have crossed this guy’s mind too. Jp Prat Projects on YouTube shared a video featuring his father’s “wood gas car,” which is actually a fleetside 1983 Chevy. It operates on a 350-cubic-inch engine that’s even older, having been manufactured in 1972, and it hasn’t consumed a single drop of gasoline in over 100,000 kilometers (or 62,000 miles).

This truck doesn’t rely on liquid fuel at all; burning wood creates carbon monoxide that combines with hydrogen to power the vintage pushrod V8. A gasifier positioned behind the cab takes about five to 10 minutes to ignite completely, after which the engine can start, idle, and drive down the road. A filter is located on the other side of the cab, with a torch in between regulated by a ball valve. It certainly has an industrial aesthetic.

Whereas you might simply turn the key halfway on a regular truck to fuel the pump, the startup process here varies significantly. It begins with a crumpled piece of newspaper placed at the base of the gasifier. An electric fan then draws the flame upwards, allowing the charcoal and fresh wood to ignite. Once the engine fires up, it automatically draws in the gas.

Regarding engine modifications, there aren’t many. He notes that they replaced the camshaft and fitted an intake manifold from a 1986 Corvette with throttle body injection. Naturally, there’s some distinct plumbing, including sections leading to a large cooler mounted at the front of the truck. This isn’t mistaken for stock, with its extensive chunk of metal that surpasses most brush guards and the dual barrels at the rear, but it was less labor-intensive than you might think.

In terms of efficiency, they report a consumption of 35 to 40 kilograms of wood per 100 km, which translates to 81 pounds for every 60 miles. You can count on a hydraulic log splitter being quite useful for them. They refill the gasifier approximately every 43 miles for safety, and if there’s a fire already going, there’s no need to re-light the newspaper. The small-block Chevy doesn’t need any alternative fuel to start, unlike some other alternative fuel systems.

And while performance isn’t the primary goal here, the host mentions that torque peaks around 2,000 rpm. A 3.42 final drive facilitates movement without excessively high revs, and a TH700 transmission with overdrive connects it to the engine. In that aspect, it’s quite a conventional setup.

You’d undoubtedly encounter more issues trying to operate something like this in Los Angeles. Who knows how a smog check technician would react if you arrived with the gasifier fully operational? Although wood can be considered a renewable fuel, the particulate emissions are significantly higher than those produced by a gasoline engine. For that reason, it wouldn’t exactly be called “cleaner.” Additionally, the energy density pales in comparison to that of gasoline.

Regardless, this stands as a fascinating example of a long-existing technology. It’s just not often seen these days. And observing it now in light of contemporary internal combustion engines makes it easy to understand why.

### Alternative Fuel Solution: Running a Classic Chevy Truck Fueled by Wood for Economic Driving

As fuel costs keep increasing and environmental issues become more pressing, numerous vehicle owners are seeking alternative fuel options. One creative method involves converting older vehicles, like classic Chevy trucks, to operate on wood gas. This strategy not only offers an economical driving solution but also fosters sustainability through the use of renewable resources.

#### Understanding Wood Gasification

Wood gasification refers to the method of converting solid wood into a combustible gas via thermal and chemical reactions. This gas, mainly made up of carbon monoxide, hydrogen, and methane, can be utilized to energize internal combustion engines. The process includes heating wood in a low-oxygen environment, breaking down the wood and releasing volatile gases.

#### Advantages of Wood Gas

1. **Affordability**: Wood typically costs less than gasoline or diesel, particularly when sourced locally or from waste products. This can significantly lower fuel expenses for truck operators.

2. **Environmental Friendliness**: Using wood as a fuel source is eco-friendly. It decreases dependence on fossil fuels and can assist in reducing greenhouse gas emissions if obtained sustainably.

3. **Energy Autonomy**: By generating their own fuel, truck owners can become less reliant on variable fuel prices and supply chain disruptions.

4. **Conservation of Classic Vehicles**: Transforming older Chevy trucks to run on wood gas can prolong their usability and maintain them operational, safeguarding classic vehicles for future generations.

#### Conversion Method

1. **Gasifier Creation**: The initial step in adapting a Chevy truck to operate on wood gas is constructing or acquiring a gasifier. This apparatus will convert wood into gas. There are numerous designs available, ranging from straightforward homemade versions to more sophisticated commercial ones.

2. **Engine Changes**: The engine of the truck may need adjustments to run effectively on wood gas. This might include tuning the carburetor or fuel injection system to fit the distinct fuel characteristics.

3. **Fuel Storage Setup**: A storage solution for the wood chips or pellets utilized in the gasifier needs to be established. This could be a basic hopper that dispenses the gasifier as required.

4. **Safety Protocols**: Safety is crucial when dealing with wood gas, as it contains flammable gases. Adequate ventilation, monitoring systems, and adherence to safety measures are vital to avert mishaps.

#### Challenges and Considerations

While using a Chevy truck on wood gas can be advantageous, there are challenges to address:

– **Efficiency**: Wood gas may not yield the same power output as conventional fuels, which can result in diminished performance.
– **Fuel Accessibility**: The ability to obtain a reliable supply of appropriate wood might be limited, especially in metropolitan areas.
– **Learning Curve**: Grasping the gasification process and managing the system may necessitate a substantial commitment of time and effort.

#### Conclusion

Driving an older Chevy truck fueled by wood gas presents a unique and sustainable alternative to conventional fuels. With potential cost savings and ecological advantages, this approach appeals to those looking to minimize their carbon footprint while enjoying the allure of classic vehicles. By adopting this innovative fuel solution, truck owners can help create a more sustainable future while keeping their cherished Chevy on the road.
