Daguo Science and Technology started from the copycat system

For this reason, many domestic and foreign netizens have even ridiculed that the senior management of Daxia Nanjing Automobile is probably going to jump out of anger.

After all, it was reported some time ago that the negotiations between Daxia Nanjing Automobile and PricewaterhouseCoopers, the asset custodian of Rover Automobile, were at the end and a contract was about to be signed.

As a result, Sugon Technology stepped in and directly added a touch of haze to the acquisition contract that was about to be completed. Why didn't this make Daxia Nanjing Automobile angry?

In this regard, Sugon Technology said that since you have not truly reached a cooperation agreement, both parties have opportunities to compete.

And looking at the history of the previous life, since Nanjing Automobile acquired Rover Motors in the previous life, the MG Motor they produced is simply difficult to describe.

For this reason, there is a saying in the automotive circle: "If you repair an airplane and repair a watch, Roewe and MG cannot repair it."

Both Roewe and MG are essentially technologies from Rover Motors, but one buyer is SAIC and the other buyer is Nanjing Automobile.

Among them, SAIC mainly bought core intellectual property rights such as Rover 25, 75, K series gasoline engines, L series diesel engines and automobile platforms.

What Nanjing Automobile purchased was the technical authorization of Rover 25, 45, 75, TF and other gasoline engines and automobile platforms, as well as automobile production lines, so Roewe and MG are essentially Rover automobiles.

Among them, SAIC bought a lot of technical intellectual property rights, and the cost was even higher, reaching 67 million pounds.

Nanjing Auto spent 53 million pounds to purchase many technology patent licenses and production equipment, which was slightly lower.

But no matter which manufacturer acquires Rover Motors, it cannot perfectly exploit the technology of Rover Motors, a century-old car company.

In the end, the statement came out that "it can't be repaired by Roewe and MG by repairing the watch from the top to the bottom of the aircraft".

Of course, they cannot be entirely blamed for this, except that the Rover car itself is too complex in design and does not consider the mood of the after-sales maintenance personnel.

The main reason is that the domestic engine and transmission processing technology and metal materials are not up to standard.

Many things that were no problem when produced in the Dayin Empire ended up being difficult to repair MG and Roewe cars after arriving in Daxia due to insufficient processing technology and metal materials.

In addition, another reason is that domestic SAIC and Nanjing Automobile have not truly grasped the essence of Rover Motors.

There is no way to develop our own engine technology based on Rover Motors' engine technology based on local conditions.

After all, the processing technology and even metal materials of the two countries are different. If the engine is just copied and barely built, why is it not difficult to repair in the end?

Of course, no matter what the situation was in the previous life, it is the past after all and has become the past.

Lin Chen in this life has also absorbed the experience of SAIC and Nanjing Automobile in his previous life, and will not follow the same pattern as SAIC and Nanjing Automobile in his previous life.

How to do it specifically?

Lin Chen is preparing to make a big move. This big move is to take a path that has not been taken before!

In terms of engines, Lin Chen is not planning to produce Rover 25, 45, 75, and TF engines adapted to local conditions, because the property rights of these engines have been acquired by SAIC.

At this time, if Sugon Technology follows the same pattern and produces Rover 25, 45, 75, and TF engines, it will have to pay patent fees to SAIC for each engine it builds.

So Lin Chen is planning to create a new engine based on Rover's engine technology. As for what this new engine is?

When the new engine was first launched in the previous life, some people said that the new engine was the terminator of electric vehicles and the ultimate savior of fuel vehicles.

Of course, this is just the initial stage of the launch. After the launch, it received negative reviews.

Because cars using that new engine were 30,000 yuan more expensive than other cars of the same model, the new engine eventually became a toy for the rich.

As for what this new engine is, it had a famous name in its previous life. Its name was the Mazda Blue Sky compression ignition engine, and it was also a spark plug controlled compression ignition engine!

The theoretical thermal efficiency of the Blue Sky compression ignition engine is as high as 50%, and its fuel consumption is 3.3 liters per 100 kilometers, which directly beats the old fuel engine.

Of course theory is theory, reality is practice!

In fact, because the spark plug controlled compression ignition engine technology is not a true pure compression ignition engine technology, it is actually difficult to maintain the theoretical thermal efficiency of 50%.

The spark plug controlled compression ignition engine in the previous generation, that is, the Blue Sky compression ignition engine, only achieved a thermal efficiency of 43%.

Although this result defeated the Fengtian engine by 41%, it won the title of highest thermal efficiency and most fuel-efficient.

But it is not as powerful as the media boasted. Therefore, after being tested by market media and users after its launch, it received negative reviews. Even the Blue Sky compression ignition engine seems to have become a product of money fraud.

After all, the price is 30,000 more, but the thermal efficiency is only 2% more than the most powerful Fengtian engine, and the actual fuel consumption saved is less than 0.5 liters.

It simply cannot reach the 3.3 liters per 100 kilometers advertised by Mazda, so how can netizens who feel they have been deceived not get angry and give negative reviews.

Of course, what Lin Chen wants to build is definitely not a spark plug controlled compression ignition engine like the previous Mazda Blue Sky engine.

Because this KitKat compression ignition engine has been proven by facts that the thermal efficiency can only reach 43%, and it cannot achieve the theoretical thermal efficiency of 50% at all.

It cannot achieve the theoretical fuel consumption of 3.3 liters per 100 kilometers. Under such circumstances, how can Lin Chen go back to the old path of Mazda Blue Sky engine.

Of course, Mazda doesn't want to directly develop a pure compression ignition gasoline engine.

After all, everyone knows that pure compression ignition engines are the most fuel-efficient and can theoretically easily achieve 50% thermal efficiency. However, the problem is that the auto-ignition point of gasoline is different from that of diesel.

For gasoline to be compressed directly to the temperature of auto-ignition, it needs to be as high as 510 degrees, while diesel only needs more than 350 degrees, which means that the compression ratio of gasoline is theoretically 1.45 times higher than that of diesel.

And such a high compression ratio simply cannot be tolerated by the engine for a long time, so only current gasoline engines have spark plugs.

After all, since compression cannot spontaneously ignite, the gasoline can be ignited directly with sparks, which solves the problem of difficulty in using gasoline.

Of course, with current human processing technology and material technology, a pure compression ignition engine cannot withstand such a high compression ratio for a long time.

But it's okay to bear it in the short term, but in the long term such a high compression ratio is a disaster.

After all, a mature engine can last at least 150,000 kilometers without major repairs, and the compression ignition engine has a too high compression ratio.

It's a disaster for pistons, connecting rods, crankshafts, cylinder walls, cylinder heads and other parts.

Therefore, the compression ignition engine has been around for decades since the theory was proposed, but in fact it cannot be put into use at all. (End of chapter)
