Lazy loading doesn't create chunk.js in Angular

I have some project and I want to use lazy loading for component. In app.module.ts file I removed from import section three record with my routing to different components. In my app-routing.module.ts I created APP_ROUTES like below:

const APP_ROUTES : Route[] = [
    { 
            path: '', pathMatch: 'full', 
        redirectTo: 'login'
    },
    { 
        path: 'cars', 
        loadChildren: 'app/cars/cars.module#CarsModule' 
    }
];

@NgModule({
        imports: [
            RouterModule.forRoot(APP_ROUTES)
        ],
        exports: [
            RouterModule
        ]
})

I have a main folder which name is cars and I pasted CarsRoutingModule from app.module.ts like I said before into cars.module.ts (section imports). I created ROUTES in my cars modul into cars-routing.module.ts like below:

const CARS_ROUTES : Route[] = [
    {
        path: '',
        component: <any> CarsComponent,
        children: [
            {
                path: '',
                component: <any>CarsListComponent
            },
            { 
                path: ':id', 
                component: <any>CarDetailsComponent,
                resolve: { car: CarResolve }
            }
        ]
    }
];

@NgModule({
        imports: [
            RouterModule.forChild(CARS_ROUTES)
        ],
        exports: [
            RouterModule
        ]
})

and I think it's ok. Ok, so I have second module login.module.ts where I pasted LoginRoutingModule from app.module.ts like I said before into login.module.ts (section imports). I created ROUTES like below:

const LOGIN_ROUTES : Route[] = [
     { 
         path: 'login', 
         component: <any>LoginComponent,
        }
];

@NgModule({
        imports: [
            RouterModule.forChild(LOGIN_ROUTES)
        ],
        exports: [
            RouterModule
        ]
})

and it looks good for me too. I compiled my project without errors. I have login screen so it good, but when I completed login and password and I am into dashboard - I don't see anything like chunk.js (into Sources tab too) like below:

Guess but correct me if I'm wrong - in angular 4+ we don't have chunk.js file? I checked something else. When I don't have lazy loading in my projekt I have more modules on my login site:

Like we can see on the left side my debugger in ng folder I have: AppModule, CarsModule, CoreModule, LoginModule, SharedModule. When I add lazy-loading in the same place like up, I have only AppModule, CoreModule and like below:

So now, can I be sure that my lazy-loading works good?
