The interior still features seats in the front and a railing in the back.

This time, given the opportunity, Lin Ying simply installed two large windows at the front of the car, as well as windows on both sides and at the rear of the vehicle.

Even the rear compartment has two five-centimeter-wide glass strips installed.

For safety reasons, Lin Ying separated the steam valve switch into two controllers.

One is a separate control that can be used to adjust the vehicle speed based on the air pressure.

The other is connected to the brakes; when the brakes are suddenly applied, the air valve will open quickly. This prevents the brakes and air valves from working in opposite directions.

The use of gears and pulleys is already quite mature.

She was also highly skilled at using small gears to drive large gears and make them operate at high speed.

However, because Lin Ying's main frame was made of wood, even though she had treated the wood and applied a waterproofing coating, wood is inherently prone to warping. Even though Lin Ying chose hardwood.

One reason is to prevent hot steam from splashing hot water everywhere, which could cause the wood to warp over time.

Another advantage is that it allows for higher utilization of the ejected gas. Lin Ying's metal windmill is enclosed. This way, the gas sprayed onto the fan blades can make the blades rotate faster.

In addition, there is a funnel-shaped device under the fan blades to collect steam water.

Thinking of the ice and snow outside, Lin Ying decided to find some hemp rope and wrap it around the wheels twice to increase friction.

After everything was assembled, the second sparkling little car officially entered the experimental stage.

One drawback of this vehicle is its slow starting speed. The vehicle needs to be warmed up before it can start running.

For safety reasons, this test drive was conducted on public roads, not in the residential compound.

She is unsure of the car's speed, and with the road icy, she cannot stop the car instantly, which could easily lead to danger.

But she couldn't leave her two children at home while she went out. So she simply tidied up the car again and wrapped the two children up tightly.

Lin Ying continued to pedal the bike.

That's right, Lin Ying added foot pedals again. Although the vehicle is now twice as heavy as before, Lin Ying is worried about what to do if the vehicle malfunctions and becomes unable to move.

For example, right now, when she's unsure of the speed, it's safer to use the pedals.

Lin Ying rode her bike onto the road and started a fire.

She had prepared sawdust in advance, put the sawdust on a winnowing basket, lit it, added fine firewood, and then added dry firewood.

After confirming that it was lit, more coal was added on top.

Then, they carefully placed the winnowing basket into the stove.

Both inner tanks are already filled with water. Now, all we need to do is wait for the water to boil and then check the car's speed.

After Lin Ying put the fire in, she kept an eye on it with her watch.

After about ten minutes, hot steam started to come out of the steam valve.

Five minutes later, Lin Ying returned to the car, released the brake, and slowly closed the valve a little. The car didn't move.

Lin Ying loosened her grip a bit more. This time, the car began to move slowly.

Little by little, the car's valve was closed, and the car's speed increased significantly.

By this time, the temperature inside the car had started to rise. The two children, wrapped in their blankets, could no longer stay still.

Lin Ying tried several times in a row: starting the car, moving it forward, and braking.

Compared to last time, Lin Ying installed shock absorber springs on this wheel. This will not only increase the ride comfort of the car but also protect the body from falling apart during driving.

However, Lin Ying wants to say that if you are not strong enough, it is best not to try this experiment.

After the car experiment concluded, Lin Ying calculated that with a full tank of water and continuous operation, it could run for an hour. That hour would cover approximately 80 kilometers.

This is sufficient to drive to town without any problem.

However, there was another problem: when she was adding coal, the chimney above blocked the air while she was driving, causing the inside of the vehicle to become filled with smoke for a moment.

Lin Ying remembered the question and planned to make changes after returning.

Having learned how to slow down, Lin Ying didn't use the foot pedal this time when she went back; instead, she simply turned on the steam engine and drove back.

Seeing that the two children were already asleep in the car, Lin Ying took them home first and then drained the water from the heater and steam. Only after the car had cooled down did she begin her investigation.

Lin Ying thought for a moment and decided to add a backward bend to the top of the chimney. This would prevent rainwater from seeping in and also prevent smoke from flowing back up as the chimney moves forward.

Of course, given the current situation, one burning is enough to reach the town, so this change is already sufficient.

After finishing these tasks, Lin Ying added a curtain to the area where the children sat in the car. This way, when she opened the door to go in or out, the children inside wouldn't immediately feel cold.

Besides that, another issue is that the car's condensation is too strong, causing fogging on the interior windows. This means she has to constantly wipe them clean while driving, which is quite inconvenient. Also, if it's snowing outside, snow easily gets onto the outside windows.

Seeing that other cars have windshield wipers, Lin Ying felt she should get one too.

This isn't difficult; it's just about making a long, narrow cover out of leather. That solves the hard part.

After that, all you need to do is assemble the pre-made windshield wipers and control them all with a single crank.
